A baseball travels at a velocity of 45.3 m/s towards second base for 17 s. Calculate the displacement of the ball.
Answer:
770.1 m
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 45.3 m/s
Time (t) = 17 s
Displacement (d) =?
Velocity is defined according to the following formula:
Velocity = Displacement /Time
With the above formula, we can obtain the displacement of the ball as follow:
Velocity = Displacement /Time
45.3 = Displacement / 17
Cross multiply
Displacement = 45.3 × 17
Displacement = 770.1 m
Therefore the displacement of the ball is 770.1 m
Answer: 770.1 gravity multiplied by time

A horizontal spring is lying on a frictionless surface. One end of the spring is attaches to a wall while the other end is connected to a movable object. The spring and object are compressed by 0.065 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 14.7 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.032 m relative to its unstrained length
Answer:
0.832 m/s
Explanation:
The work done by the spring W equals the kinetic energy of the object K
The work done by the spring W = 1/2k(x₀² - x₁²) where k = spring constant, x₀ = initial compression = 0.065 m and x₁ = final compression = 0.032 m
The kinetic energy of the object, K = 1/2mv² where m = mass of object and v = speed of object
Since W = K,
1/2k(x₀² - x₁²) = 1/2mv²
k(x₀² - x₁²) = mv²
mv² = k(x₀² - x₁²)
v² = [(k/m)(x₀² - x₁²)]
taking square root of both sides, we have
v = √[(k/m)(x₀² - x₁²)] since ω = angular frequency = √(k/m),
v = √[(k/m)√(x₀² - x₁²)]
v = ω√(x₀² - x₁²)]
Since ω = 14.7 rad/s, we substitute the other variables into the equation, so we have
v = 14.7 rad/s × √((0.065 m)² - (0.032 m)²)]
v = 14.7 rad/s × √(0.004225 m² - 0.001024 m²)]
v = 14.7 rad/s × √(0.003201 m²)
v = 14.7 rad/s × 0.056577
v = 0.832 m/s

You are 100% right for question a and you have a good start on b!
Explanation:
For (ii) of part a, you could also say that since the friction force is in the opposite direction of the pushing force, that the friction is '-60N' The negative sign just shows the direction of friction relative to the pushing force. But for the magnitude the signs are not important.
For part b,
work done equals force × distance
w = F×d
In this case, the worker is pushing with 60 newtons, and the distance is 28m.
Therefore,
w = 60N×28m
w = 1680j
(Or 1.7kj)

A force of 20 N acts upon a 5000g block. Calculate the acceleration of the object
Answer:
a = 4 m/s²
Explanation:
Given: 5000 g, 20N
To find: Acceleration (a)
Solution: Firstly, convert 5000g to kilograms
1000g = 1kg
∴ 5000g = 5kg if divided by 1000
A = F ÷ m
= 20 ÷ 5
= 4 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

___ is the total movement capacity of a joint. Object grip Object grip Range of motion Range of motion Joint flexion Joint flexion Joint extension
Answer: Range of motion
Explanation:
Range of motion can be defined as the extent to which joint can move and cause the movement of the arms and legs. It measures the degree to which the limb can make up a circle. A joint is formed by the connective of two or more bones. The range of motion can be active, passive, assess, preserve and others. Some joints do not allow motion of the limbs example fibrous joints between sutures of skull. Shoulder joints are most flexible joints.

Does sound travel faster in a warm room or a cold room? Explain your answer.
Answer:
The speed of sound is greater in hot air than it is in cold air. This is because the molecules of air are moving faster and the vibrations of the sound wave can therefore be transmitted faster. This means that when sound travels from hot air to cold air or from cold air to hot air it will refract.
