A 2.1 kg object is moving due East at 32 m/s on a frictionless, horizontal sufrace. When the first object strikes a second, stationary 3.6 kg object, the 2.1 kg object rebounds at 8.0 m/s in a direction 29 degrees north of west. What percentage of the original kinetic energy of the system is converted into other forms of energy during the collision?

An elastic collision takes place between a 0.050-kg toy car moving at 10 × 10² m/h and a 0.014-kg toy car moving at 20 × 109 mm/yr.  What is the kinetic energy of the system? Express your answer with the appropriate units.

Two blocks of clay, one of mass 1.00 kg and one of mass 6.00 kg, undergo a completely inelastic collision. Before the collision one of the blocks is at rest and the other block is moving with kinetic energy 32.0 J. If the 6.00 kg block is initially at rest and the 1.00 kg block is moving, what is the initial speed of the 1.00 kg block?

A 92 kg boulder , moving at 5.0 m/s attempts to pass directly across the adit of a mine. Just as the boulder reaches the end of the adit, it was met head-on in midair by two 75 kg miners, both moving in the direction opposite the boulder. One is moving 2.0 m/s, the other at 3.0 m/s . They all become entangled as one mass. What is their velocity after the collision? 18. What is the momentum of a 18 kg object traveling at a constant velocity that has 295 J of kinetic energy?

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 4.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 7.0 m/s. What is the final velocity of the glider A after collision?

The figure below shows a bullet of mass 15 g traveling horizontally towards the east with speed 250 m/s, which strikes a block of mass 1.5 kg that is initially at rest on a frictionless table. After striking the block, the bullet is embedded in the block and the block and the bullet move together as one unit. What is the energy loss in the system due to this collision

A stationary firecracker explodes into two pieces. The piece shot to the right has a mass of 0.07 kg and is traveling 45 m/s. How fast is the smaller 0.04 kg piece, which travels to the left? Ignore friction and air resistance.

The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0190 kg and is moving along the x axis with a velocity of +4.08 m/s. It makes a collision with puck B, which has a mass of 0.0380 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B. (a) Number (b) Number At rest B 65 A 37 B Before collision After collision Units Units

A 3-kg object moving with a velocity of 7 m/s in the positive x direction strikes and sticks to a 3-kg object moving with a speed of 2 m/s in the same direction. How much kinetic energy is lost in this collision?
