Question

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

Answer 1

u=20m/s
v=0m/s
t=10s
a=(v-u)/t=-2m/s2
retardation=2m/s2
retarding force=2400*2=4800N

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
