A crate with a mass of 155 kg starting from rest, slides down a ramp making an angle of 32 degrees with respect to horizontal. The ramp is 6 meters long. A constant frictional force of 200 N acts throughout the motion and a force F is being applied by a rope as shown to prevent the block from sliding too fast. Suppose that while traveling at v=0.1 m/s down the ramp, at d=4meters from the end of the ramp, the rope breaks, Use the work-kinetic energy theorem to calculate the speed, in m/s, of the crate when it touches the bottom of the ramp.
A string attached to two objects passes over a pulley with negligible mass. Object 2’s mass is greater than object 1’s mass.

Part 2) Repeat for the case of a pulley with non-negligible rotational inertia
Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 50 N/m, attached to a 30-kg block in an incline (θ=30°). With the spring initially at equilibrium position, the block was pushed 0.5 meters up the incline by a 50-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.5, determine the: a) normal force (in Newtons) b) work done by the spring (in Joules)

To get up on the roof, a person (mass 72.0 kg) places a 6.80 m aluminum ladder (mass 13.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The top of the ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2.00 m from the base, as measured along the ladder. The person is standing on the ladder 3.00 m from the base, as measured along the ladder. Find the normal reaction and friction forces (in N) on the ladder at its base. (Enter the magnitudes.)

A student struggled with his first midterm exam and is slightly angry. For this reason he drops a 10 kg object on the good teacher from a height of 5 m. When seeing the object fall to the ground, the teacher asks the logical question: How much will the internal energy of the box have increased after hitting the ground? If the specific heat of the box is cp = 3 kJ / kg.K How much will the temperature of the box have increased?

An arborist is cutting down a tree a 28 m high tree bystarting his cut 1.8 m above the ground. The tree has a mass of 3750 kg. The tree trunk can be thought of as a uniformly dense, thin rod. 1. What's the speed of the tree’s center of mass when the trunk is parallel to the ground on its way down. The tree rotates about the point where it is cut., 1.8 m above the ground. 2. What is the total amount of kinetic energy that the tree has at thatpoint of parallelism to the ground? How fast would a 950.0 kg truck have to be traveling to have the same kinetic energy as the tree?
