Question

Two people push a 2,000-kg car to get it started. An acceleration of at least 5.0 m/s? is required to start
the car. Assuming both people apply the same magnitude force, how much force will each need to
apply if friction between the car and the road is 300 N? (5150N)

Answer 1

This question deals with the concepts of NEWTON'S SECOND LAW OF MOTION and frictional force.

The magnitude of force required by each person will be "5150 N".

Applying Newton's Second law formula to get the total force required to produce given acceleration.

F = ma

where,

F = required force = ?

m = mass of the car = 2000 kg

a = acceleration = 5 m/s²

Therefore,

F = (2000 kg)(5 m/s²)

F = 10000 N

Now, the friction force will be added to this required force. Because to get the car starting to move, the friction force first needs to be overcome.

F = 10000 N + frictional force = 10000 N + 300 N

F = 10300 N

Now, this is the force that both people need to apply. In order to find the force applied by the single individual, we can simply divide this force into two.

F = $\frac{10300\ N}{2}$

F = 5150 N
