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 satellite rotates starting from rest for 2.9 seconds with an angular acceleration of 4.5 rad/s2. How many revolutions has the satellite undergone in this time interval? Your answer should have one decimal place.

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

A car of mass 1200.0 kg and a truck of mass 9000.0 kg collide along a straight road. The initial speed of the car is 25.0 m/s and the initial speed of the truck is 20.0 m/s. If the speed of the car after the collision is 18.0 m/s, what is the speed of the truck after the collision? can you explain this as you solve.

A small compact car with a mass of 1000 kg is traveling north towards an intersection at a speed of 15 m/s. A truck with a mass of 2000 kg is traveling east at 10 m/s on the cross street approaching the same intersection. The two vehicles collide and stick together. a. What is the magnitude and direction of the velocity of both vehicles after the collision? b. How much energy was lost during the collision?

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...

A car with mass MC = 1.26 x 103 kg runs into the back of a truck with mass MT = 3.23 x 103 kg that is initially at rest. Immediately after the collision, the car is moving with a speed of 1.09 m/s and the truck is moving with a speed of 3.29 m/s, both in the direction the car was initially traveling. What is the total kinetic energy lost in the collision? (Of course, the change in energy...

5. A runaway truck with a mass of 2100 kg strikes a car of mass 1350 kg, which was at rest before the collision. The car’s wheels are locked during the entire event, but the truck has no brakes, i.e., it is rolling freely on the road. The two vehicles move forward together, and the car’s tires leave skid marks for a distance of 1.5 m. Suppose that the coefficient of kinetic friction between the car’s tires and the road...
