A box is pulled 2.0 meters along a rough surface at constant velocity using 100 N of force inclined at 30° above the horizontal. a. How much work is done by the: gravitational force, normal force, and frictional force? b. If the force applied, Fa, is doubled but the frictional force remains the same (this is unlikely to occur in practice since Fn changes), will the net work be the same? c. If Fa is doubled with the frictional force unchanged, how much kinetic energy would the block have after being pulled 2.0 m?

You shoot a bullet aiming to a far away tree. The bullet is 15.0 g and it embedded 15.0 cm into the trunk of a tree. If the speed of the bullet just before entering the tree is 120.0 m/s, a) How much work is done by the average force? b) what is the average force exerted on the bullet by the tree? c) What is the average acceleration of the bullet in the tree?
C 4. A box is being pulled across a rough floor with a force P. What can you say about the work done by pulling force, normal force, friction, and gravitational force? 0, W by normal force > 0, Wby friction 0, Why normal force 0, W by normal force= D. Wby pulling force <0, Why normal force = 0, W by friction <0, W by gravitational force = 0 0, W by friction <0. Wby gravitational force = 0

A constant 112.-N force acts on a 3.81-kg box. The box initially is moving at 24.9 m/s in the direction of the force, and 3.72 s later the box is moving at 71.1 m/s. Determine the work (in J) done by this force. You may assume that the box experiences constant acceleration, but do not assume that only one force acts on the box.
