Two identical 1350-kg automobiles A and B are at rest with their brakes released when B is struck by a 5500-kg truck C which is moving to the left at 8 km/h. A second collision then occurs when B strikes A. Assuming the first collision is perfectly plastic and the second collision is perfectly elastic, determine the velocities of the three vehicles just after the second collision. (Round the final answers to two decimal places.) - 8 km The velocity...

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...

A truck with a mass of 1300 kg and moving with a speed of 12.0 m/s rear-ends a 843 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second A 61.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped...

Two identical cars A and B are at rest on a loading dock with brakes released. Car C, of a slightly different style but of the same weight, has been pushed by dock workers and hits car B with a velocity of 1.75 m/s. Knowing that the coefficient of restitution is 0.8 between B and C and 0.5 between A and B. determine the velocity of each car after all collisions have taken place (Round your answer to three decimal...

A truck with a mass of 1710 kg and moving with a speed of 14.0 m/s rear-ends a 613 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. m/s truck m/s car As shown in the figure below, object m, = 1.50 kg starts...

Two identical cars A and B are at rest on a loading dock with
brakes released. Car C, of a slightly different style but of the
same weight, has been pushed by dockworkers and hits car B with a
velocity of 4 m/s. Knowing that the coefficient of restitution is
0.8 between B and C and 0.5 between A and B, determine the energy
lost as a result of the series of collisions. (Round the final
answer to three decimal...

Two bodies, A and B each of mass 2.0 kg moving with velocities vA = (2.0i ˆ + 5.0j) m/s and vB = (1.0i ˆ – 5.0j) m/s collide and stick together. After the collision, what is the velocity of the composite object?

1. A 3000 kg truck travelling at 50 km/hr strikes a stationary 1000 kg car, locking the two vehicles together. A) What is the final velocity of the two vehicles? B) How much of the initial kinetic energy is lost to the collision? 2.What is the gravitational force between two masses of mass 30 lbs and 50 lbs, separated by a distance of 2 meters? 3.
