Question

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

Answer 1

Answer:

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

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

$\Delta p=F\times \Delta t$

Where, F = force

t = time

Put the value into the formula

$\Delta p=690\times6.6$

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

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