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
