Calculate the time required for a 6000 Newton net force to stop a 1200 kg car initially traveling at 10 meter per second.

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver
