List of top Physics Questions on Relative Velocity asked in KEAM

The velocity of a swimmer in the direction of flow of river is \(10 \, \text{kmh}^{-1}\) and that against the flow of river is \(6 \, \text{kmh}^{-1}\). The velocity of the swimmer in still water in \(\text{kmh}^{-1}\) is
A boat is moving from the east bank to the west bank on a south flowing river. If the speed of the boat is 4 km/h and that of the river is 3 km/h. If the width of the river is 2 km, the distance travelled by the boat is
A train of length $L$ moves with a constant speed $V_t$. A person at the back of the train fires a bullet at time $t=0$ towards a target which is at a distance of $D$ (at time $t=0$) from the front of the train (on the same direction of motion). Another person at the front of the train fires another bullet at time $t=T$ towards the same target. Both bullets reach the target at the same time. Assuming the speed of the bullets, $V_b$, are same, the length of the train is
A person from a truck, moving with a constant speed of $60$ km/h, throws a ball upwards with a speed of $60$ km/h. Neglecting the effect of rotation of Earth, choose the correct answer from the given choices
A man rides a bicycle with a speed of \( 17.32 \text{ m s}^{-1} \) in east-west direction. If the rain falls vertically with a speed of \( 10 \text{ m s}^{-1} \), the direction in which he must hold his umbrella is
A bus is moving with a velocity of 10 ms\(^{-1}\) on a straight road. A scooterist wishes to overtake the bus in one minute. If the bus is at a distance of 1.2 km ahead, then the velocity with which he has to chase the bus is
