2. A 0.50 kg baseball approaches a bat at 25 m/s. If it is in contact
with the bat for 0.005s, then rebounds at 25 m/s, what is the average
contact force between the ball and the bat?

Answer:
impulse = change in momentum
F × t = change in momentum
F × t = m ∆V
F × t = m { 25 - ( - 25 ) }
F × 0.005 = 50 m
F × 5 / 1000 = 50 × 0.5
F = 5000 N
YOOOODA:
my answer key says its -500 N ?

Answer:
5000 N
Explanation:
mΔv = Ft
m(final velocity - initial velocity) = Ft
0.50 [25-(-25)] = F(0.005)
25 = F(0.005)
5000 = F
the initial velocity is negative because it is going in the opposite direction was the final, it can be though of as going south or down
