Jeremy accidently dropped his toy stuffed animal from the balcony of his apartment on the fourth floor. The toy hit the ground at a velocity of 16.0 meters/second. At impact, it took 2.0 seconds for the toy's velocity to reach 0 meters/second. If the toy has a mass of 0.25 kilograms, what's the force of the impact?

F = (mass) (acceleration) = ma

m = 0.25 kg

Vi = 16 m/s

t = 2 s

Vf = 0 m/s (since it was put to stop)

a = (Vf-Vi) / t

a = (0-16) / 2

a = 8 m/s^2 (decelerating)

F = ma = (0.25 kg) (8 m/s^2)

F = 2 N

Hope this answer will be a good h elp for you.
