R

. Both continue to move with the same speed of

65 k m h^{-1}

Which of the following options is correct for given statements? (i) Both cars have the same velocities even if the car turns towards town

Q

(ii) Two bodies have same velocities if they are moving with same speed in different directions.

Q3PhysicsUnit 2: Kinematics

A boy sitting on the top most berth in the compartment of a train which is just going to stop on a railway station, drops an apple aiming at the open hand of his brother situated vertically below his hands at a distance of about

2 \mathrm{m}

The apple will fall
