Question

a ball was thrown vertically upwards from the ground .if we went up to the height of 50m and then came down to the ground.how long it was in the air​

Answer 1

Step-by-step explanation:

Sorry to say : Perhaps this question is not of Maths. Physics probably...

You need to find the time of flight i. e. the time during which the ball is in air.

From 3rd equation of motion v^2 - u^2 = 2(-g)h

Final Velocity is zero

Initial velocity by which the ball is thrown is 31.62m/s

Now from 1st equation of motion v = u + (-g)t

Time is 3.162s
