Two masses collide and stick together. Before the collision one of the masses was at rest. Is there a situation in which the kinetic energy is conserved in such a collision?
A: Yes, if the less massive particle is the one initially at rest.
B: Yes, if the more massive particle is the one initially at rest.
C: Yes, if the two particles have the same mass.
D: No, kinetic energy is always lost is such a collision.
A: Yes, if the less massive particle is the one initially at rest.
B: Yes, if the more massive particle is the one initially at rest.
C: Yes, if the two particles have the same mass.
D: No, kinetic energy is always lost is such a collision.
举一反三
- What are the two purposes of sleeping There are two purposes of sleeping: physical rest and rest.
- Block A has mass 1.00 kg and block B has mass 3.00 kg. The blocks collide and stick together on a level, frictionless surface.After the collision, the kinetic energy (KE) of block A is A: 1/9 the KE of block B B: 1/3 the KE of block B C: 3 times the KE of block B D: 9 times the KE of block B E: the same as the KE of block B
- At the opposite extreme(相反的极端) from a perfectly elastic collision(理想弹性碰撞) is one in which the colliding bodies(物体) stick(粘) together as would two lumps of putty(油灰块).
- (The more) kinetic (energy in) the particles of (a material), the (hottest) the material is.（） A: The more B: energy in C: a material D: hottest
