A 0.017-kg bullet is fired into a stationary block of wood of mass of 4.7 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded on the block of wood). If the speed of the bullet before collision is 472 m/s, what is the kinetic energy of the bullet-plus-wood combination right after the collision? Assume no change in the potential energy of the system before and after the collision. Express your answer in two decimal places, in Joules.

A 65 kg person rides a 20 kg bicycle at a speed of 11 m/s. The cyclist runs into a parked car and comes to a fast stop.

In the figure here, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 3.3 kg, encounters a coefficient of kinetic friction HL = 0.52 and slides to a stop in distance di = 0.32 m. Piece R encounters a coefficient of kinetic friction µR = 0.49 and slides to a stop in distance dr = 0.49 m. What was %3D the mass of the block? -μ = 0 - dg-

A 0.01 kg bullet moves at a constant speed of 500 m/s and collides with a 1.5 kg wooden block initially at rest. The surface of the table is friction-less and 0.7 m above the floor level. After the collision the bullet becomes embedded into the block. The bullet-block system slides off the top of the table and strikes the floor. What is the resulting kinetic energy of the bullet and block system just before impact with the ground?

A 30 kg box with a height of 0.230 meters is on top of a 0.5-meter-high table and is initially at rest. A 5kg projectile having a speed of 20 m/s was launched at the horizontal ground, 6.972 meters (horizontal distance) away from the nearest vertical wall of the box. When the projectile hit the vertical side of the box, it rebound at a speed of -11.143 m/s and the box developed a speed of 5.140 m/s. At what angle was the projectile launched?
