Question

A car weighing 2400 kg and moving with a velocity of 20m/s is stopped in 10s on applying brakes calculate the retardation

Answer 1

Explanation:

Hello...

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
