Question

A car of mass 24000kg moving with a velocity of 20 m/s is stopped in 10 sec on applying brakes . Calculate the retardation and retarding force

Answer 1

f(dt)=m(v-u)
f(10)=24000(0-20)
f(10)=-480000
f=-480000/10
f=-48000N

Answer 2

Hey there!

Given,

Mass = 24000 kg

Inital velocity = 20 m/s

Time = 10 second

Retardation =?

Retarding force =?

Retardation = initial velocity/time

= 20/10

= 2 m/s^2

Retarding force = mass x retardation

= 2400 x 2

= 48000 N
