Question

A 2 metric ton body is moving with a velocity of 54km/h. Find the change in momentum of the body when it stops. if it stops in 15s, calculate the retarding force​

Answer 1

Explanation:

$\huge\bold\pink{answer}$

m=2000kg

u=54km/h =15 m/s

v=0

t=15 sec

now

change in momentum= m(v-u)= 2000(0-15)=

= -30000kg m/s

F = m(v-u)/t

= -30000/15

F = -2000N
