Q7.

A stone thrown from the top of a building is given an initial velocity of 20.0 m/s straight upward. The height of the building is 50.0 m. determine the velocity in m/sec when the stone hits the ground. g =9.8 m / 



Answer : Option B
Explaination / Solution:

When the stone ll reach at the same point from where is was thrown it ll have same velocity but with opposite sign. 

So  initial velocity u = -20 m/s

Final velocity before hitting ground = v

Distance covered s = 50 m

Acceleration due to gravity a = 9.8 m/s​​​​​​2

We know






As this velocity is in opposite direction is initial velocity so sign ll be negative.

v = -37.1 m/s
