Question

A car of mass 1200 kg is brought to rest from a speed of 60 m/s by a constant breaking force of
6000N. Calculate the retardation.​

Answer 1

Answer: 5 m/s^-2

Explanation:

We know that ,

Force = ma ( m = Mass & a = Acceleration )

Here, Force = 6000 N

Mass (m) = 1200 Kg

Acceleration (a) = ?

So on substitution of values in above equation we get

6000 = 1200 × a

a = 5 m/s^-2
