Question

a car is travelling around a road. it passes point A at a constant speed of vms-1 and drives for t seconds at this speed. it then accelerates at a constant rate for 6 until it reaches speed of 2v ms-1. maintaining this speed, it arrives at point b after a further 2t seconds. the total distance travelled between A and B was 528m and the average speed was 20ms. find v and t​

Answer 1

Explanation:

There is a tendency to believe that if an object is moving at constant speed then it has no acceleration. This is indeed true in the case of an object moving along a straight line path. On the other hand, a particle moving on a curved path is accelerating whether the speed is changing or not
