Two men pushing a stalled car generate a net force of +698 N for 7.37 s. What is the final momentum of the car?
Force x Time = Impulse = Momentum change
Since the initial momentum was zero, just multiply the two numbers for the final momentum.
5144.26
To find the final momentum of the car, we need to use the formula:
Momentum = Force × Time
Given:
Net force = +698 N
Time = 7.37 s
Substituting the values into the formula, we get:
Momentum = 698 N × 7.37 s
Calculating the multiplication, we find:
Momentum = 5140.26 Ns.
Therefore, the final momentum of the car is 5140.26 Ns.
To calculate the final momentum of the car, we need to use the equation:
Momentum = Force × Time
In this case, the net force applied to the car is +698 N (a positive value indicates that the force is in the same direction as the motion), and the time for which the force is applied is 7.37 s.
Therefore, we can calculate the momentum as follows:
Momentum = 698 N × 7.37 s
To find the final result, simply multiply the force and time values together:
Momentum = 5138.26 N·s
So, the final momentum of the car is 5138.26 N·s.
