Questions 1.-4. refer to a head-on collision between two balls with the following initial values: Before Collision m2 V Ix 3.5 kg 4.5 kg 5.0 m/s -2.0 m/s 1. What is the total momentum (in kg m/s) of the system? 2. If the two balls stick together, what is their common speed (in m/s) after they collide? 3. How much kinetic energy (in joules, positive number) was lost in this collision? 4. If the two balls do not stick together, and the first ball moves at vịx = -1 m/s after they collide, what is the speed (in m/s) of the second ball?

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…

meteor moving through the Earth's atmosphere has a momentum of 1.15 x 104 kgm/s. As it falls, friction with the atmosphere slows it to 1/4 its original speed, as its mass shrinks to 2/9 of its original mass. Determine its new momentum. A. 320 kgm/s B. 639 kgm/s C. 10350 kgm/s D. 207000 kgm/s

Physics: Unit: Momentum and collisions Consider a collision in one dimensional that involves two objects of masses 4.5 kg and 6.2 kg. The larger mass is initially at rest, and the smaller mass has an initial velocity of 16 m/s (E). The final velocity of the larger object is 10.0 m/s (E). Calculate the final velocity of the smaller object after the collision.(Hint: = m1Vi1 + m2Vi2 = m1Vf1 + m2Vf2)
