behind in midair. What is their final speed, in meters per second,

dove’s speed is 7.5 m/s in the same direction?
2.) a.) A bowling ball of mass mb = 3.7 kg is
rolled down the lane with a velocity of v1 =
2.8 m/s. It strikes a single remaining pin mp =
0.92 kg head on. After the collision the bowling ball has a
velocity (in the same direction) of v2 = 1.65
m/s. Write an expression for the velocity of pin in the horizontal
direction after the impact, vp.
b.) What is the pins speed in m/s?
c.) Assuming the coefficient of friction is μk
= 0.1, how far in meters could the pin slide before stopping if it
doesn't topple?
