Describe the rise and fall of a basketball using the concepts of kinetic energy and potential energy.

Answers

Answer:

in the beginning the kinetic energy is at a maximum level because the starting velocity is high comparatively.. and because of the gravitational acceleration acting on the ball in the opposite direction the kinetic energy drops proportionally because of the velocity drop. after the ball reaches it's maximum height the potential energy of the ball is high because of the height.. and again the kinetic energy starts to build because the ball again starts to fall down..

a car of mass 800 kg is travelling at 12m/s the car accelerates over a distance of 240 m there force causing this acceleration is 200 newton determine the work done on the car and its final velocity car

Answers

Answer:

See below

Explanation:

Force X distance = work

 200 N * 240 m = 48 000 N-m = 48 000 j

F = ma

200 = 800 a

a = 1/4 m/s^2

d = v t  + 1/2 a t^2

12 m/s t  + 1/2  1/4 m/s^2  t^2 = 240

                shows t = 17 sec  (via Quadratic Formula)

final velocity = 12 + at = 12 + 1/4(17) = 16.26 m/s

Without using a micrometer screw gauge, how do I find the average diameter of a long piece of thin wire using a metre rule and a uniform glass rod?​

Answers

Answer:

Wind the long piece of thin wire around the uniform glass rod multiple times, find the length of the total diameters using the metre ruler, and divide by the number of times you wound it around the rod.

Explanation:

Since the diameter of one long piece of thin wire is too thin to be measured by a metre ruler, you can wind it multiple times and push it side by side to get a length you can measure.

For example, if you wound it around 20 times and the total length of 20 diameters of the wire side-by-side is 2.0 cm, one winding, which is the diameter would be 2.0cm ÷ 20 = 0.10cm or 1mm.

The graph in the question that represents an object with constant acceleration is : Graph A

Description of constant acceleration

Acceleration is the change in velocity with time. For graph A the acceleration remained constant as the velocity of the object did not change with the change in time. As the time changes from 4 to 9 seconds the velocity of the object remained at 40 before decelerating to 0.  This shows that the acceleration of the object was constant.

what is the force needed to accelerate a grocery sack weighing 212 N upward at 1.7 m/s2

Answers

Answer:

Explanation:

A block of mass 3. 0 kg is hung from a spring, causing it to stretch 12 cm at equilibrium, as shown above. The 3. 0 kg block is then replaced by a 4. 0 kg block, and the new block is released from the position shown above, at which the spring is unstretched. How far will the 4. 0 kg block fall before its direction is reversed?.

Answers

Based on the length of the spring and the mass of the block, the distance the 4.0 kg block can fall before a reversal in direction is 32 cm.

How do we arrive at 32cm?

Because energy is conserved, the distance the block can drop can be found as:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

Spring constant:

= (Mass x gravity)  / distance

= (3 x 9.8) / 12

= 2.45 cm

Distance is:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

distance = (2 x Mass x gravity) / spring constant

= (2 x 4 x 9.8) / 2.45

= 32 cm

an object from 10.0 meters. She knows it had 50.0 joules of potential energy. How much mass does it have?

Answers

Answer:

5N

Explanation:

Work done by a constant force is given by the following equation:

W=F⋅d⋅cos(θ)

where F is the applied force, d is the distance over which the force is applied, and θ is the angle between the force and displacement vectors.

In this case, the work is done by gravity, and as the object is assumed to fall straight down, θ=0^o.

We know that the force of gravity acting on an object can be expressed by FG=mg, and for an object which is not accelerating (e.g. a stationary object), this is equal to the object's weight.

We know d=10m,θ=0^o and W=50J, so we can solve for F to find the object's weight. ⇒F=Wdcos (θ) But cos (0^o)=1, so: F=Wd=50J10m=5N

a roller coaster of mass 2000kg is rolling down a track with an instantaneous speed of 10m/s

Answers

The given is:

The given is:Mass – 2000 kg

The given is:Mass – 2000 kgInstantaneous speed – 10 meter per second

Step: 1

Step: 1K.E= 1/2mv^2

Where, K.E – Kinetic energy in joules:

m – Mass in kg

  v – Velocity or speed in meter per second

Step: 2

From the give,

m = 2000 kg

v = 10 m/s

Equation (1) becomes,

K.E= 1/2 (2000) (10)^2

= (0.5)(2000)(100)

= 100000

K.E = 100,000 Joules

The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s.
