A pickup truck with mass 18• 105 gm is traveling eastbound at 15 m/s, while a compact car (900 kg) is traveling westbound with-15 m/s. The vehicles collide head-on, becoming entangled. a. Find the speed of the entangled vehicles after the collision. b. Find the change in velocity of each vehicle. c. Find the change in kinetic energy d. If the mass of both the vehicles were doubled, calculate how would the final velocity and change in kinetic energy be affected?

You are in your car driving on a highway at 23 m/s when you glance in the passenger side mirror (a convex mirror with radius of curvature 150 cm) and notice a truck approaching. If the image of the truck is approaching the vertex of the mirror at a speed of 1.5 m/s when the truck is 2.0 m away, what is the speed of the truck relative to the highway?

You are in your car driving on a highway at 25 m/s when you glance in the passenger- side mirror (a convex mirror with radius of curvature 150 cm) and notice a truck approaching. At a certain distance away, the image of the truck approaching the vertex of the mirror and the truck relative to the highway speeds are 2.0 m/s and 52 m/s, respectively. Find how far away was the truck?

A state trooper is traveling down the interstate at 30 m/s. He sees a speeder traveling at 70 m/s approaching from behind. At the moment the speeder passes the trooper, the trooper hits the gas and gives chase at a constant acceleration of 2.5 m/s 2 Part A Assuming that the speeder continues at 70 m/s, how long will it take the trooper to catch up to the speeder? Express your answer in...
