A car starts from rest and accelerates at 
. At 
, a ball is dropped out of a
window by a person sitting in the car. What is the velocity and acceleration of the ball at 
? (Take, 
) [NEET 2021]

Text Solution
Verified by ExpertsThe correct answer is:
A
Given,
Initial velocity, 
Acceleration, 
Velocity at 
At this time a ball is dropped out of a window by a person sitting in the car. The velocity of ball after 
is given by
Vertical velocity of
Horizontal velocity of ball, 
So, magnitude of velocity of ball
Acceleration of the ball will be equal to gravitational acceleration g. i.e.
