Question

A man moves on his motorbike with 54 km/hr and then takes a U-turn and continues to move with same velocity. The time of U-turn is 10s. Find the magnitude of average acceleration during U-turn.

Answer 1

Acceleration=velocity/time
Since velocity is in kmph,we convert it to mps
ie.,54×5/18=15 mps
therefore acceleration=15/10=1.5m/s square

Answer 2

Hint : use the co ordinate system......
