Question

A ball moves on a smooth floor in a straight line with a uniform velocity 10ms for 6s At t6s the ball hits a wall and comes back along the same line to the starting point with the same speed Draw the velocitytime graph and use it to find the total distance travelled by the ball and its displacement

Accepted Answer

To find the total distance distance travelled in the first 6 seconds and the next 6 seconds must be calculated Distance covered in 6s velocity x time 10 x 6 60 ms Distance covered in the next 6s velocity x time 10 x 6 60 ms Total distance covered in a matter of 66 12 seconds is 60 60 120m As the ball returns to the initial point the displacement is zero
