Question

A car of mass 1000 kg moving with a velocity of
36 km/h comes to rest in 5 seconds. What is the force
exerted on the car ?​

Answer 1

Answer:

7200N

Step-by-step explanation:

force required to stop a car

F= Ma (M is mass and a is acceleration)

a= v/t

=36/5

=7.2

F=Ma

=1000×7.2

F=7200N

Answer 2

Answer:

mass of car is = 1000g

velocity = 36km/h

time = 5 second

Force = ?

Step-by-step explanation:

Force = ?

Force = mass x acceleration

= 1000 x 36 divide by 5

= 3600 ➗ 5

= 720

hence force exerted on car is the 720 N
