8. Calculate the magnitude of force required to stop a car moving with a velocity of 30 m/s
in 10 seconds. The mass of the car is 1,500 kg.
[Ans. 4500 N
mass 4 kg. If the same force acts on​

Answer 1

Answer:

Here,

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
