Question

A strongman applies a constant force of 2000 N to a car of mass 1000 kg, which is initially at rest. (a) What is the acceleration of the car? (b) How far does the car move in 5 s?

Answer 1

(a) Acceleration
`a=2m/sec^2`

(b) Distance s = 25 m

Step-by-step explanation:

We have given constant force F = 2000 N

Mass of the car = 1000 kg

(a) From newton's law we know that F = ma

So
`2000=1000* a`

`a=2m/sec^2`

(b) Tine is given as t = 5 sec

As the car is initially at rest so initial velocity u = 0 m/sec

From second equation of motion
`s=ut+(1)/(2)at^2`

So
`s=0* 5+(1)/(2)* 2* 5^2=25m`
