A box has a mass of 4 kg and is dropped from a certain height (h), it falls to the floor with a speed of 25 m / s. It is asked to determine: a. The kinetic energy of the box hitting the floor, and the height h from which it is dropped. b. The kinetic energy of the box hitting the floor, and the height h from which it is dropped if the stone is inside a sealed room that minimizes the effect of gravity. (use an acceleration of gravity of 5.31 ft / s 2 for this subsection).
Problem 3: A 75-kg box at rest is pulled by a force of 350 N acting parallel to the ground. Using the work and energy principle, determine the distance travelled by the box by the time its speed reaches 10 m/s. The coefficient of kinetic friction between the crate and the ground is 0.25.

A 5.00 kg block is released from rest on a ramp that is inclined at an angle of 60.0° below the horizontal. The initial position of the block is a vertical distance of 2.00 m above the bottom of the ramp. (a) If the speed of the block is 5.00 m/s when it reaches the bottom of the ramp, what was the work done on it by the friction force? (b) If the angle of the ramp is changed but the block is released from a point that is still 2.00 m above the base of the ramp, both the magnitude of the friction force and the distance along the ramp that the block travels change. If the angle of the incline is changed to 50.0°, does the magnitude of the work done by the friction force increase or decrease compared to the value calculated in part (a)? (c) How much work is done by friction when the ramp angle is 50.0°?

2.5 rad/s A simple pendulum is set into motion at two different times with different initial conditions. The first time: the bob is in its equilibrium position and is given an initial velocity + 2 m/s. The maximum height reached by the bob is h1.max and the period of motion is T1. The second time: the bob is in its equilibrium position and is given an initial velocity + 4 m/s The maximum height reached by the bob is h2.max and the period of motion is T2. Assume that the motion is simple harmonic, which of the following is true? 9h nax and T, = T| 1.0max h2max= 9h, ax and T = 3I

A 498-gram ball is traveling horizontally at 11.1 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and initially travel at 8.8 m/s to the right. If the bat produced an average force of 1.3 kN on the ball, for how long (in milliseconds) was it in contact with the ball?
