Question

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? Use F = ma, where .
The force of the impact is _____
newtons.

Answer 1

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
