Question

Two men pushing a stalled car generate a net force of +690Nfor

6.6 sec. What is the final momentum of the car?

Answer 1

The final momentum of the car is 4554 kg m/s.

Step-by-step explanation:

Given that,

F = 690 N

Time = 6.6 sec

Momentum :

The momentum is the product of the force and change of time.

We need to calculate the final momentum

Using formula of momentum

`\Delta p=F* \Delta t`

Where, F = force

t = time

Put the value into the formula

`\Delta p=690*6.6`

`\Delta p=4554\ kg-m/s`

Hence, The final momentum of the car is 4554 kg m/s.
