02. Relative Velocity in Plane
Motion in Plane

143753 A man sitting in a train in motion is facing the engine. He tosses a coin-up; the coin falls behind him. The train is:

1 Moving forward with acceleration
2 Moving forward with uniform speed
3 Moving backward with deceleration
4 Moving backward with uniform speed
Motion in Plane

269950 An aeroplane moving in a circular path with a speed \(250 \mathrm{~km} / \mathrm{h}\). The change in velocity in half of the revolution is.

1 \(500 \mathrm{~km} / \mathrm{h}\)
2 \(250 \mathrm{~km} / \mathrm{h}\)
3 \(120 \mathrm{~km} / \mathrm{h}\)
4 zero
Motion in Plane

269951 A car starting from a point travels towards east with a velocity of \(36 \mathrm{kmph}\). Another car starting from the same point travels towards north with a velocity of \(24 \mathrm{kmph}\). The relative velocity of one with respect to another is

1 \(12 \sqrt{13} \mathrm{kmph}\)
2 \(30 \mathrm{kmph}\)
3 \(12 \mathrm{kmph}\)
4 \(20 \mathrm{kmph}\)
Motion in Plane

269952 A ship is moving due east with a velocity of \(12 \mathrm{~m} / \mathrm{sec}\), a truck is moving across on the ship with velocity \(4 \mathrm{~m} / \mathrm{sec}\). A monkey is climbing the vertical pole mounted on the truck with a velocity of \(3 \mathrm{~m} / \mathrm{sec}\). Find the velocity of the monkey as observed by the man on the shore (m/sec)
