Question

A ball of mass 500 g is moving with a velocity of 50 m s-1. The ball is brought to rest by applying a constant force for 0.2 s. Calculate the force applied.

Answer 1

Answer:

mass = 500

velocity = 5 ms-1

constant of Force = 0.2

for applied =500/5

100/0.2

50

Answer 2

Explanation:

given: m= 500 g = 0.5 kg

u= 50 m/s

v= 0

t= 0.2 s

solution: a= v-u/t

0-50/0.2

a= -250 m/s^2

f= ma

0.5 * -250

= -125 N
