A 1425 kg truck driving at 13.0 m/s collides elastically with a stationary 1175 kg car. If the car is traveling 14.25 m/s just after the collision, what is the velocity of the truck immediately after the collision? Assume that this is a perfectly elastic collision. Round your answer to the hundredths place. Final velocity of the truck = m/s

6. You are driving a 1250 kg car at a velocity of 21.0 m/s and a 9.00 g bug splatters on your window. Before the collision, the bug was traveling at a velocity of 2.00 m/s directly towards you. What is the change in velocity of your car due to the collision with the bug?

A 1000-kg car moving at 30m/s due north collides completely elastically with a 1250-kg truck heading north of east. After the collision the truck is moving due north and the car is moving due east. Find the initial speed of the truck. I think the answer is 34m/s and we have to break it up into x and y component and equate them but please tell me the theory behind it. Thanks

A. A truck (mass 3274 kg) and a car (1559 kg) collide. The truck moves at a speed of 53 m/s towards the stationary car. Assuming this is an elastic collision, how fast will the bruck be going after the collision? Answer as a whole number. B.A cylinder initially traveling at 3 m/s rolls up a hill inclined at 48 degrees. What is its vertical height when it comes to rest? Give your answer to one decimal place. C. A...

A car of mass 2400 kg collides with a truck of mass 4500 kg at the intersection of horizontal roads. The vehicles stick together and slide immediately after the collision. The x- and y-components of the car’s velocity just before the collision are (36, 0) m/s, respectively, and the same components of the truck’s velocity just before the collision are (-15, 25) m/s. a. calculate the x component of the velocity of the combined car and truck immediately after the...
