List of top Physics Questions on Relative Velocity asked in BITSAT

A passenger sitting in a train A moving at 90 km/h observes another train B moving in the opposite direction for 8 s. If the velocity of the train B is 54 km/h, then length of train B is:

A 2 m wide truck is moving with a uniform speed v₀ = 8m/s along a straight horizontal road. A pedestrian starts to cross the road with a uniform speed v when the truck is 4 m away from him. The minimum value of v so that he can cross the road safely is

A boy running on a horizontal road at 8km/h finds rain falling vertically. He increases his speed to 12km/h and finds the drops make 30^∘ with the vertical. The speed of rain with respect to the road is:

A \(2\,\text{m}\) wide truck is moving with a uniform speed \(v_0 = 8\,\text{m/s}\) along a straight horizontal road. A pedestrian starts to cross the road with a uniform speed \(v\) when the truck is \(4\,\text{m}\) away from him. The minimum value of \(v\) so that he can cross the road safely is:
