A) i) Displacement = 0 ; since the initial and final position of the body are same.
ii) Distance travelled = 2h ; since the body goes up to height h and comes down by an equal distance.
B) Retardation is the act or result of delaying.
For example :- Velocity of vehicle decreases when brake is applied.
