An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.15 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 35.5 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? m/s

Answer:

6.83 m/s

Explanation:

Momentum is conserved.

Initial momentum = final momentum

(300 g) (-2.15 m/s) + (22.5 g) (35.5 m/s) = (22.5 g) v

v = 6.83 m/s
