Question

at time t=2.3s, a 4kg OURCES Test Bank, Question 1 At time t 2.3 s, a 4-kg block that initially moves with a constant speed of 6 m/s undergoes an inelastic collision with another block. Any two inertial observers must agree that the event took place at t = 2.3 s. the momentum of the two block system is conserved during the collision. the initial speed of the block is 6 m/s O the initial momentum of the block has magnitude 24 kg-m/s the second block is moving after the collision.

Explanation / Answer

RIGHT ANSWER:

":The Momentum of the two Block system is conserved during the collision."

Reason: For Inertial Observers "Newtons Laws are applicable", But they may be moving with high speed, so there may be time dilation, and the velocities of the 2 blocks will be with respect to the velocity of the Inertial Observer, and therefore initial momentum also will be based on relative speed
