Question

Our car is moving with a uniform velocity of 30 m/s, it is stop in

in 2 second by applying a force of 1500 Newton through its breaks

calculate the change in momentum of car the retardation

produced by car the mass of the car​

Answer 1

Answer:

Explanation:

Given :

Initial velocity, u = : 30m/s

Force 1500 N =

Time, t = 2 sec

To find :

The change in momentum and the retardation in car.

Solution :

Using the first equation of motion,

V = u - at

where, v is final velocity,

minus sign for retardation.

putting the values,

0 = 30-a * 2

a = 15 m/s²
