Given:
Uniform velocity of the car, v = 54 km/h
(a)KE of the boy = (1/2)mv2
(b) Similarly we can get the KE of the boy at the different instant of time with respect to the given value of uniform velocities.
Now to draw the graph you don't need any rocket science decide velocity as on X-axis and KE as on Y-axis divided with suitable class and mark all the 4 corresponding points on the graph and witness the parabola curve since
KE ∠V2
