what is the maximum velocity of an 89.0–kg person bouncing on a bathroom scale having a force constant of 1.63×106 n/m, if the amplitude of the bounce is 0.170 cm?
The maximum velocity of an 89.0 kg person bouncing on a bathroom scale having a force constant of 1.63 x 10^6 N/m is 31.1 m/s.
The above situation represents a case of Simple Harmonic Motion(SHM).
Following are some general equations of SHM :
ω = √k/√m
Here ω is the angular frequency
k is the force constant
m is the mass of the body
And the maximum velocity is given by the formula,
v = ω^2 x A
Where A represents the amplitude
Putting the given values in the above equation,
v = k/m x A
V = 1.63 x 10^6 x 0.17 x 10^-2/ 89
v = 31.1 m/s
Hence, the maximum velocity of an 89.0 kg person bouncing on a bathroom scale having a force constant of 1.63 x 10^6 N/m is 31.1 m/s.

A proton in an accelerator attains a speed of 0.845 . what is the magnitude of the momentum of the proton?
The magnitude of the momentum of the proton is 4.233 × 10⁻¹⁹ kg m/sec
Momentum can be calculated by using the formula,
Momentum = Mass × Velocity
For this proton we have,
Mass of proton is a constant = 1.67 × 10⁻²⁷ kg
Velocity = 0.845 c, where c is the constant speed of light.
Velocity = 0.845 × 3 × 10⁸
Velocity = 253.5 × 10⁶ m/sec
Substitute with the mass and velocity to calculate the momentum as follows:
Momentum = 1.67 × 10⁻²⁷ × 253.5 × 10⁶
Or, momentum = 4.233 × 10⁻¹⁹ kg m/sec
Hence, the momentum of the proton is 4.233 × 10⁻¹⁹ kg m/sec.

Suppose you are looking at two graphs of velocity vs time. The first graph is of an object undergoing constant positive acceleration of 2 m/s², and the second graph is of an object undergoing constant positive acceleration of 4 m/s². How do the graphs compare?(1 point)
A. Both graphs are linear with positive slopes, but the second graph has a steeper slope than the first graph.
B. Both graphs are constant, horizontal lines, but the second graph has a higher constant line than the first graph.
C. Both graphs are linear with positive slopes, but the first graph has a steeper slope than the second graph.
D. Both graphs are constant, horizontal lines, but the first graph has a higher constant line than the second graph.
Answer:
Both graphs are linear with positive slopes, but the second graph has a steeper slope than the first graph. I just took the quick check so I know the answer from Connexus.
Explanation:
Since the first graph goes over 1 second and up 2 meter/s then that would mean it is less steep than the graph that goes over 1 second and up 4 m/s; so this rules out option A. Now for C and B, it says a constant "Horizontal line" which would be wrong for the case because the slopes are not going sideways, the slopes in the question are going in a slanted vertical constant motion. I hope this helps!
Both graphs are linear with positive slopes, but the second graph has a steeper slope than the first graph, therefore the correct answer is option A.
What is acceleration?
The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².
As given in the problem Suppose you are looking at two graphs of velocity vs time.
The first graph is of an object undergoing constant positive acceleration of 2 meters/second², and the second graph is of an object undergoing constant positive acceleration of 4 meters/second².
The second graph has a higher slope than the first, but both graphs are linear with positive slopes, thus option A is the right response.

A car is moving with an acceleration of 8.5 m/s^2. It starts from rest and travels when the force of 7000 N is applied. What is the mass of the car?
the mass of the car is 823.52 kg.
When a force is applied to a body, the momentum's magnitude, direction, or both can change. One of the most significant laws in all of physics is Newton's second law. F = ma, where F (force) and a (acceleration) are both vector values, can be used to represent a body whose mass m is constant. We can deduce a relationship between forces F and acceleration a from Newton's second law (via mass). The F is always the RESULTANT force on the item, and that is the important part. F=0 if there is no acceleration of the item.
Due to that,
F=7000 N
a=8.5 m/s²
we know that
F=ma
mass= 7000/8.5
=823.52 kg
Consequently, the mass of the car is 823.52 kg.

A friend of yours tells you that electric potential and voltage are the same thing. should you correct her, and if so, how?
I’d correct her in this way.
Electrical potential is the amount of energy acquired or lost per unit of charge when a charge is moved away from a reference point where the potential is assumed to be zero. Voltage is the difference in potential between any two places, where the potential may or may not be zero.
Suppose that point A's potential is 10000 volts and point B's potential is 10100 volts with respect to a stated reference point that is sometimes an infinite distance away. So 100 volts of voltage will exist between B and A.

A 30-g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?.
The momentum of the car is 4620 cm/s.
The momentum of an object is defined as the product of the mass of the object and its velocity. Momentum is denoted by the symbol 'M'. It is presented in the unit meter per second. Velocity is defined as the distance divided by time. It is also presented in the unit meter per second.
Mass of the car = 30 g
Height of the hill = 12 cm
Speed of the car = 154 m/s
Distance traveled by car = 275 cm
The momentum of the car is,
Momentum = Mass × Velocity
M = m × v
= 30 × 154
= 4620 cm/s
Therefore, the momentum of the car is 4620 cm/s.
