Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

4) An archer draws his compound bow and shoots an arrow. The 25 g arrow leaves the bow with a
velocity of 95 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the
arrow through a displacement of 57 cm. The peak draw weight of the bow is 312 N. (This is the
maximum force that the archer has to exert on the bowstring.)
a. How much kinetic energy does the arrow have after release?
b. If shot straight up, how high will the arrow go?

A. Calculate the work done by the force of gravity when a 5.0kg object is lifted to a height of 30.0m above the ground B. Calculate the velocity with which the object strikes the ground if dropped from that height, using the principle of conservation of energy C. Calculate the kinetic energy and the potential energy of the object at a halfway on the path after it is dropped. To do this part, you need to find the velocity of the object at that position using an equation of motion. What is the total energy of the object at that point? Does this verify the principle of conservation of energy?
