Passage / Comprehension

A balloon rises up with constant acceleration of 10 m/s² from earth's surface at t = 0 After 4 seconds a particle drops from the balloon.

Displacement of particle in time interval $0 \leq t \leq 4 s$ is :-

Answer:

Solution:

Displacement of particle in $0 \leq t \leq 4 s =$ Displacement of balloon in first 4 seconds

$= ut + \frac{1}{2} at^{2} = 0 + \frac{1}{2} (10) (4)^{2} = 80 m$
