Need help with Conservation of Momentum Physics Problem?
A 0.18 kg baseball moving at +27 m/s is slowed to a stop by a catcher who exerts a
constant force of −370 N.
a) How long does it take this force to stop
Answer in units of s.
b) How far does the ball travel before stopping?
Answer in units of m

a) impulse = F*Δt = m*Δv
-370N * Δt = 0.18kg * -27m/s → Δt = 0.013 s
b) Lots of ways to proceed. How about
change in KE = work done
-½ * 0.18kg * (27m/s)² = -370N * d → d = 0.18 m
