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.
I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 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 3.00 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 2.00 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.
IV. Same lump is thrown towards another wall, and this time the wall moves when the lump sticks to it (it's a very thin wall). You can model this situation where the "wall" has a mass of 0.500 kg and is attached to the spring with spring constant k = 4.00 N/m.
(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.
(d) Calculate the maximum compression of the spring.
