For how long a time must a tow truck pull with a force of 550N on a stalled 1200kg car to give it a forward velocity of 2.0m/s?

4.36 seconds

Explanation:

According to the question;

Force is 550 N Mass of the car is 1200 kg Velocity of the car is 2.0 m/s

We are needed to find the time the car must the tow track pull the car.

From Newton's second law of motion; Impulsive force, F = Mv:t, where m is the mass, v is the velocity and t is the time.

Rearranging the formula;

t = mv : F

Thus;

Time = (1200 kg * 2.0 m/s²) : 550 N

= 4.36 seconds

Thus, the time needed to pull the car is 4.36 seconds
