NATA Mock Test - 7 - Question 4

A balloon is moving upwards with a speed of 20 m/s. When it is at a height of 14 m from ground in front of a plane mirror in as shown in figure, a boy drops himself from the balloon. Find the time duration for which he will see the image of source S placed symmetrically before plane mirror during free fall.

Detailed Solution for NATA Mock Test - 7 - Question 4

FC = 2 + 10 = 12 m

The boy has dropped himself at point F. So, his velocity is 20 m/s in upward direction.
Let us first find the time to move from F to topmost point and then from topmost point to point C. From

Solving this equation we get, t1 = 4.53 s.
Velocity of boy at point Q,
(v2 = u2 - 2gh)
Time taken to move the boy from Q to topmost point and then from topmost point to Q will be.

∴Time required time is : t = t1 - t2 = 1.7 s
