A 1120 kg car experiences an impulse of 30,000.0 N · s during a collision with a wall.If the collision takes 0.43 s,what was the velocity of the car just before the collision?

Question

Quizplus · Accepted Answer

Impulse is equal to the change in momentum, which is mass times velocity. The impulse given is 30,000 N·s, and the mass of the car is 1120 kg. Using the formula impulse = mass × velocity, we solve for velocity: velocity = impulse / mass = 30,000 N·s / 1120 kg = 26.79 m/s, which rounds to 27 m/s.
