A 1-kg pellet travels with velocity 200 m/s to the right when it collides with a 39-kg hanging mass which is initially at rest. After the collision, the pellet remains lodged in the hanging mass, i.e., it is a completely inelastic collision. The hanging mass (+pellet) then swings upward and reaches a maximum height hmax before swinging downward again. Assume that no external forces are present and therefore the momentum of the system is conserved.  a) What is the velocity vf of the hanging mass + pellet immediately after the collision? calculate in m/s b) What is the final kinetic energy Kf of the hanging mass + pellet immediately after the collision? calculate in J c) What is the maximum height hmax of the swinging hanging mass + pellet in centimeters? calculate in cm

A 2-kg pellet travels with velocity 20 m/s to the right when it collides with a 38-kg hanging mass which is initially at rest. After the collision, the pellet remains lodged in the hanging mass, i.e., it is a completely inelastic collision. The hanging mass (+pellet) then swings upward and reaches a maximum height hmax before swinging downward again. Assume that no external forces are present and therefore the momentum of the system is conserved. What is the velocity vf of the hanging mass + pellet immediately after the collision? What is the final kinetic energy Kf of the hanging mass + pellet immediately after the collision? What is the maximum height hmax of the swinging hanging mass + pellet in centimeters?

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

A pendulum of length L = 0.98 m hangs at rest with  2.0 kg bob. The string is of negligible mass.  A smaller 0.10 kg mass is traveling to the left at 20.0 m/s and has an elastic collision with the pendulum bob. Assume that positive is to the right. a) What is the velocity of the bob immediately after the elastic collision?

Same situation as before. This time it s a block of mass 1.45 kg sliding with a constant velocity of 4.84 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.08 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision. What will be the speeds of the 1.45-kg and 4.08-kg blocks, respectively, after their SECOND collision with one another?     0.92 m/s and 2.65 m/s     2.30 m/s and 7.88 m/s     3.44 m/s and 0.90 m/s     3.12 m/s and 4.39 m/s
