Question

sketch a velocity time graph for the motion of the body from the graph explaining each step, calculate total distance covered by the body.

Answer 1

8/32 = 1:4

Explanation:

Distance covered is equal to the area under the velocity-time graph.

Distance in last two seconds S₂ = 1/2 x 8 X 2 = 8m.

Total distance = 1/2 X 8 X (6+2) = 32m.

The fraction of the distance covered by the body in the last two seconds of its motion to the total distance traveled by it in all the seven seconds is

8/32 = 1:4
