Question

if a car decelerates from 40 m per second to 10 metre per second in 3 second then deceleration for the body would be equal to

Answer 1

solution:

initial velocity, u= 40m/s

finl velocity, v= 10m/s

time taken, t= 3 sec.

acceleration, a=?

a= v-u/t

= 10-40/3

= -10/3= -3.3m/s^2

so, retardation = 3.3 m/s^2
