Question

A car of mass 2400 kg moving with a velocity of 20 m/s is stopped in 10 seconds on applying brakes. Calculate the retardation and retarding force.

Answer 1

I think this is the answer

Answer 2

Hey there!

Given,

Mass = 2400 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

= 4800 N
