A 1000kg car moving at 15m/s to the right collided head-on with another 1500 kg car who was coming in the opposite direction at a speed of 20m/s. After collision the two cars interlocked to each other, and the wreckage dragged with a new speed. What is the lost of kinetic energy during the collision ? A 1000 kg moving at 15 m/s to the right collided head-on with another 1500 kg car who was coming in the opposite direction...
A 1500-kg car is moving westward with a speed of 20m/s and a 3000-kg truck is traveling east with a speed of 16 m/s. Find the velocity of the center of mass of the system. Let east be the positive x-direction.
13. Suppose a car of mass 100 kg is moving with a speed of 20 m/s. How much KE does it carry? If a truck of mass 2000 kg is moving with a same speed what is it Kinetic energy?
A 1500 kg car begins Wing down a 5.0 inclined road with a speed of 30 km/h. The engine is turned off. After the car has traveled 50 m along the road, its speed is 40 km/h (a) How much is the mechanical energy of the car reduced because of the net frictional force? (b) What is the magnitude of that net frictional force?

A blue car with mass mc = 481 kg is moving east with a speed of vc = 23 m/s and collides with a purple truck with mass mt = 1289 kg that is moving south with a speed of vt = 10 m/s . The two collide and lock together after the collision. *What is the magnitude of the initial momentum of the car? *What is the magnitude of the initial momentum of the truck? *What is the magnitude...
At what speed does a 1500 kg compact car have the same kinetic energy as a 1.60×104 kg truck going 24.0 km/hr ?
A 1200-kg car is moving at 16.0 m/s due north. A 1500-kg car is moving at 20.0 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. 1) Determine the speed of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.) m/sm/s 2) Determine the direction of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.)
In a crash test, a car with a mass of 1500 kg is initially moving at a speed of 18 m/s just before it collides with a barrier. The final speed of the car after the collision is zero. The original length of the car is 4.48 m, but after the collision, the smashed car is only 3.86 m long. Making the very rough approximation that the large force that the barrier exerts on the car is approximately constant during...
