PUBE: DATE: A particle is moving in a straight line with constant acceleration. it passes point p with speed of 2ms. ten seconds later passes point q. the distance between p and q is 40 metres. find the speed of particle as it passes point q.

4m/s

Explanation:The car is moving with constant acceleration therefore average speed is equal to distance over time to find the distance covered we multiple the speed by the time which gives 20 metres meaning after every 20 metres it uses a speed of 2m/s so for 40 metres it's going to be 40 x2 over 20 giving us 4m/s
