Figure shows a boy on a horizontal platform A on a smooth horizontal surface, holding a rope attached to a box B. Boy pulls the rope with a constant force of 50 N. (boy does not slip over the platform). The combined mass of platform A and boy is 250 kg and that of box B is 500 kg. The velocity of A relative to the box B, 5 s after the boy on A begins to pull the rope, will be

Options:

Answer:

Solution:

$a_{1} = \frac{1}{5} m/ s^{2} v_{1} = 5 \times \frac{1}{5} = 1 m/s a_{2} = \frac{1}{10} m/ s^{2} v_{2} = 5 \times \frac{1}{10} = \frac{1}{2} m/s$
