Block A of mass 10kg slides along a smooth horizontal surface at 2.0ms−1 and collides elastically with block B of mass 1.0kg that is moving in the same direction with a speed of 1.0ms−1. Treat the motion as one-dimensional and ignore any external forces.
a. (i) Calculate the velocities of both blocks immediately after the collision.
b. (ii) Determine the fraction of the initial kinetic energy of block A that is transferred to block B as a result of the impact.
c. (iii) Briefly comment, with numerical support from your answers, on whether such a collision is suitable for efficient energy transfer from a heavy body to a light body.
