Question

A car of mass 1500 kg is moving with speed 30 m/s. How much work done is required to stop car. If it travels 3 m before it stops find force applied on car?{plzz answer fast}.​

Answer 1

Answer:

4500 Newton

Explanation:

initial velocity of car(u)=0ms

−1

final velocity of car (v)=30ms

−1

time(t)=10s

we know,

v=u+at

30=0+a(10)

a=3ms

−2

we know,

F=ma

=1500×3

or F=4500N
