Calculate the force required to impact a car a velocity of `30m//s`, in 10 seconds. The mass of the car is `1500kg`

A

5000 N

B

7500 N

C

4500 N

D

NONE

Text Solution

Verified by Experts

The correct Answer is:
C
Hence, force required,F=?, final velocity, `v=30m//s`, time taken, `t =10 s`
initial velocity, u = 0, mass of car, `m = 1500kg`
As `F=ma =(m(v-u))/t =(1500(30-0))/10= 4500N`
