Answer:
The work done by you, W = 9800 J
Step-by-step 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
