A small object at rest is let to slide straight down a 35° incline. After 0.45 m its speed is measured to be 1.6 m/s. Use the work-energy theorem to calculate the coefficient
of kinetic friction between the object and the incline plane. Hint: Draw the free-body
diagram of the object.
A) 0.54
B) 0.35
C) 0.39
D) 0.89
E) 0.56

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
