A man weighing 80 kg is standing on a trolley weighing 320 kg. The trolley is resting on frictionless horizontal rails. If the man starts walking on the trolley along the rails at a speed of 1 m/s relative to trolley, then after 4 s, his displacement relative to the ground will be :
- 4.2 m
- 4.8 m
- 3.2 m
- 3.0 m
Answer
