Which type of collisions are most likely to occur at curves on mountains, and why?

Which of the following statements is true about the total kinetic energy of a system following an inelastic collision?

In an elastic collision between two objects, what physical quantities are conserved in this collision?

When two objects with different masses ($m₁$ and $m₂$) collide, how do the magnitudes of the forces they exert on each other during the collision compare?

Which of the following best distinguishes an elastic collision from an inelastic collision?

A Volkswagen Bug and a Volvo truck have a head-on collision. Which statement is true about the forces experienced by each vehicle during the collision?

Which of the following is the best example of an elastic collision?

Which of the following best describes the difference between an elastic collision and an inelastic collision?

In the context of types of collisions, what primarily causes both changes in motion and changes in shape of colliding objects?

Which of the following statements is true for an inelastic collision?

Two cars of masses $m_1$ and $m_2$ are moving toward each other with velocities $v_1$ and $v_2$ respectively. They collide and stick together. What is the magnitude of the final velocity of the combined cars after the collision?

When two vehicles arrive at an intersection with 4-way stop signs and collide, which type of collision is most likely to occur between them?

If the collision is perfectly elastic, which of the following statements is true?

A fake hockey puck of mass 4m has been rigged to explode. Initially the puck is at rest on a frictionless ice rink. Then it bursts into three pieces. One chunk, of mass m, slides across the ice at velocity vî. Another chunk, of mass 2m, slides across the ice at velocity 2v ĵ. Determine the velocity of the third chunk.

A massless spring with spring constant k is placed between a block of mass m and a block of mass 3m. Initially the blocks are at rest on a frictionless surface and they are held together so that the spring between them is compressed by an amount D from its equilibrium length. The blocks are then released and the spring pushes them off in opposite directions. Find the speeds of the two blocks when they detach from the spring.
