Question

You were driving a car with velocity

You were driving a car with velocity m/s. You quickly turned and braked, and your velocity became m/s. The mass of the car was 1100 kg. What was the (vector) change in momentum during this maneuver? Pay attention to signs. What was the (vector) impulse applied to the car by the ground? If the maneuver took 5 seconds, what was the the average (vector) force exerted on the car? (The net force is due to the ground and the Earth; the y components of these forces cancel.)

Explanation / Answer

a)
P = m* delta V =1100*(6,0,6)
P=(6600,0,600) kg m/s

b) zero.
almost the earth velocity os zero.

C)F= m* dv /dt
