Two tourist A and B who are at a distance of
40 km from their camp must reach it together in
the shortest possible time. They have one bicycle
and they decide to use it in turn. ‘A’ started
walking at a speed of 5 km hr–1 and B moved on
the bicycle at a speed of 15 km hr–1. After moving
certain distance B left the bicycle and walked
the remaining distance. A, on reaching near the
bicycle, picks it up and covers the remaining
distance riding it. Both reached the camp together.
(a) Find the average speed of each tourist.
(b) How long was the bicycle left unused?
A particle is travelling on a curved path. In an interval At its speed changed from v to 2v. However, the change in magnitude of its velocity was found to be AV = 15 v. What can you say about the direction of velocity at the beginning and at the end of the interval (At)?
