A car is parked on a hill. The gravitational force on the car is 9.31 x 103 N straight downward, and the angle of the hill is 4° from the horizontal. The car’s brakes fail, and the car slides 30.0 m downhill. a) Calculate the component of the gravitational force that acts parallel to the car’s motion.  b) Calculate the work done on the car by gravity as the car slides.

A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 30.0 ∘ with respect to the horizontal, as shown in the figure. A force of magnitude F = 12.5 N applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. Part A The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all forces as the block moves a distance L = 2.70 m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest. Part B What is Wg, the work done on the block by the force of gravity w⃗  as the block moves a distance L = 2.70 m up the incline? Part C What is WF, the work done on the block by the applied force F⃗  as the block moves a distance L = 2.70 m up the incline?   Part D What is WN, the work done on the block by the normal force as the block moves a distance L = 2.70 m up the inclined plane?

An object of mass m can only move on the +z axis. It is subjected to a force in the +z direction given by F(x) = the origin. a. How much work does this force do if the object moves from z = a b. If at a the block had an initial velocity of magnitude vo in the +z direction, what is its velocity at b if no other force is acting on the object? am where a is a constant and z is the distance from to z = b?
