The pulley arrangements of figures (a) and (b) are identical. The mass of the rope is negligible. In Fig. (a), the mass m is lifted up by attaching a mass 2m to the other end of the rope. In Fig. (b), m is lifted up by pulling the other end of the rope with a constant downward force F=2mg. The acceleration of m is the same in both cases.

A rocket is moving in a gravity free space with a constant acceleration of 2ms −2 , along + x direction (see figure). The length of a chamber inside the rocket is 4 m. A ball is thrown from the left end of the chamber in + x direction with a speed of 0.3ms −1 relative to the rocket. At the same time, another ball is thrown in -x direction with a speed of 0.2ms −1 from its right end relative to the rocket. The time in seconds when the two balls hit each other is
