Calculate the impulse of a bicyclist (100.0 kg) who is traveling 8 mph in the y-direction and is hit by a car that was traveling at 15 mph in the x-direction at the same time. The bicyclist's new speed is 15 mph 90 degrees in the x-direction (the y-direction is unaffected). What was the force applied by the car?

A 1300 kg car moving at 5.4 m/s is initially traveling north in the positive y direction. After completing a 90° right-hand turn to the positive x direction in 4.1 s, the inattentive operator drives into a tree, which stops the car in 280 ms. What is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? What is the magnitude of the average force that acts on the car (c)...

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s
and a 1500 kg pickup is traveling north toward the same
intersection. The car and truck collide at the intersection and
stick together. After the collision, the wreckage (car and truck)
moves off in a direction of 44.0° above the x-axis.
Determine the initial speed of the truck and the final speed of
the wreckage in meters...
