Object 1 of mass m₁, moving with a velocity v₁ collides with object 2, mass m2 at rest. If object 1 and 2 have equal masses (think of a billiard cue ball colliding with an object ball), which of the following is true after collision? O Object 1 will bounce back with half its original speed while object 2 will remain at rest. O Object 1 will stop while object 2 will be moving with a velocity equal to v₁. O Object 1 will bounce back with half its original speed while object 2 will move with a speed 0.5v1. O Object 1 will be moving with half its original speed while object 2 will be moving with a velocity equal to v₁.
A simple pendelum made of a pendelum bob of mass, m1=.0250 kg, and a string of length, l= .720m, is pulled back to an angle of theta = 35 degrees and then released from rest. At the bottom of the swing m1 and m2=.0200 kg collide and stick together. a. What is the speed of m1 immediately before it hits m2? b. What is the speed of m2 immediately after the collision? c. How high above the bottom of the swing do the two masses rise?
A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom. After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What was the height of the ramp, assuming that m1 started from rest? b.) How fast were the combined masses m1 and m2 moving after sticking together?
Two masses undergo a front-to-back colli- sion. The masses are mi m, with initial velocity 2v0, and m₂ = 4m, with initial ve- locity vo. Due to the collision, they stick together, forming a compound system. 20 Vo G m₁ If m= 2.2 kg and vo= 3.9 m/s, find the magnitude of the loss in kinetic energy after the collision.

A high-jumper, having just cleared the bar, lands on an air mattress and comes to rest. Had she landed directly on the hard ground, her stopping time would have been much shorter. Using the impulse-momentum theorem as your guide, determine which one of the following statements is correct. O The air mattress exerts the same impulse, but a greater net average force, on the high-jumper than does the hard ground. O The air mattress exerts a greater impulse, and a greater net average force, on the high-jumper than does the hard ground. O The air mattress exerts a smaller impulse, and a smaller net average force, on the high-jumper than does the hard ground. O The air mattress exerts a greater impulse, but a smaller net average force, on the high-jumper than does the hard ground. O The air mattress exerts the same impulse, but a smaller net average force, on the high-jumper than does the hard ground. MacBook Air Com
