100 POINTS!! Please help A girl places a stick at an angle of 60.0° against a flat rock on a frozen pond. She pushes at
an angle and moves the rock horizontally for 2.00 m across the pond at a velocity of 4.00 m/s
and a power of 160.0 W. What force did she apply to the stick? How much work did she do?
Your response should include all of your work and a free-body diagram.

(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?
