Question

A ball thrown up vertically upwards with a velocity of 45 m/sec, returns back to me thrower in 6 s. Assuming there is

no air friction, plot a graph between velocity and time. From the graph calculate (i) the deceleration, (ii) the acceleration, (iii)

the total distance covered by ball and (iv) the average velocity.​

It rises to a height of 50 m and comes back to the thrower, The total distance covered by the ball is zero. The net displacement of the ball is zero. The displacement is 100 m.
