You push down on the car to provide more friction for the tires allowing the cars tires to propel it forward 5 meters. How much work do you do?

The work done by you, W = 9800 J

Explanation:

Given data,

The displacement of the car, S = 5 m

Let the mass of the car be, m = 2000 kg

Let the coefficient of static friction be 0

Hence, no frictional force is acting on the tire and ground.

Let, you push down the car to provide more friction, μₓ = 0.1 (you can change the value)

In order to provide the static friction, you push down the car is equal to the static friction force,

Fₓ = μₓ · η

Where,

η - normal force acting on the car (mg)

Substituting the values,

Fₓ = 0.1 x 2000 x 9.8

= 1960 N

Therefore work done,

W = Fₓ x S

= 1960 N x 5 m

= 9800 J

Hence, the work done by you, W = 9800 J
