Question

A car is moving on a straight road at a uniform acceleration. The velocity of the car at different times is given below. Draw its velocity-time graph and calculate its acceleration and also find out the distance covered by it in 30 seconds. t Time (s) 10 20 30 40 50 v speed (m/s) 5 10 15 20 25 30 ​

Answer 1
