Kinetic energy is only conserved in an inelastic collision. True False Two objects collide ans stick...
Collisions are classified as elastic (kinetic energy is conserved), inelastic (kinetic energy is lost) or completely inelastic (the objects stick together after collision). Give an example of each type of collision. Is momentum conserved in each case?
Two objects collide and stick together. Which of the following is correct? (A) Neither momentum nor kinetic energy is conserved, (B) Both momentum and kinetic energy are conserved, (C) Momentum is conserved, but kinetic energy is not conserved, (D) Kinetic energy is conserved, but momentum is not conserved
16. In a perfectly elastic collision Kinetic Energy is conserved for the system. (Remember that elastic collisions are ones where the objects bounce off of each other and don't stick.) On an air hockey table two identical pucks collide. Initially one is at rest and the other is moving with a speed of v. (Hint: How can the concept of momentum help with this problem?) a. What is the speed of each puck after the collision in terms of the...
Contrast and compare elastic and inelastic collisions. Question 4 options: Both elastic and inelastic collisions have conservation of momentum if there are no outside forces. They are different in that elastic collisions bounce and inelastic collisions stick, and kinetic energy is conserved in inelastic collisions. They are basically the same thing, except the units are different. Elastic collisions do not have conservation of momentum and inelastic collisions have conservation of momentum if there are no outside forces. They are different...
1. Two objects collide and stick together. Kinetic energy Select one: a. unable to determine with the information. b. Kinetic energy is conserved. c. Kinetic energy is not conserved. d. is conserved only if the environment is frictionless. 2. A ball of mass 0.10 kg is dropped from a height of 12 m. Its momentum when it strikes the ground is Select one: a. 2.4 kg·m/s. b. 1.8 kg·m/s. c. 1.5 kg·m/s. d. 4.8 kg·m/s. 3. If you double the...
Question 1 (2 points) Consider two objects that collide head-on and stick together as a result of the collision. What kind of a collision is this? Inelastic O Potential Elastic O Kinetic
One object is moving and one object is at rest. The two objects then collide in a dimensional, completely inelastic collision. So the two objects stick together after the collision and move off with a common velocity. Momentum of the two-object system is conserved. The masses of the two objects are 5.00 kg and 8.50 kg, respectively. The speed of the moving object masses 5.00 kg before the collision is 22.5 m/sec. Find the final speed of the two-object system...
True and False 1. If two particles of different masses have equal kinetic energy they also have equal momentum. 2. If the momentum of a single particle is zero, its kinetic energy may not be zero. 3. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 4. A large force always produces a larger impulse on a body than a smaller force. 5. If the kinetic energy of a single particle is zero, its momentum must...
