ASK YOUR TEACHER A 7.80 g bullet is initially moving at 620 m/s just before it penetrates a block of wood to a depth of 5.80 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the block of wood? Use work and energy considerations to obtain your answer. (b) Assuming the frictional force is constant, how much time (in s) elapses between the moment the bullet enters the block of wood and the moment it stops moving?

When mass M is at the position shown, it is sliding down the inclined part of a slide at a speed of 1.91 m/s. The mass stops a distance S2 = 2.1 m along the level part of the slide. The distance S1 = 1.23 m and the angle θ = 36.90°. Calculate the coefficient of kinetic friction for the mass on the surface.
