Question

A stone is thrown vertically upwards to break a mango from the tree, at a height of 20 m from the ground. If it takes 2 sec to reach the mango, the initial speed of the stone, with which it was thrown upwards is m/s?) _m/s. (take g = 10)​

Answer 1

Answer:

height= 20m

time=2s

final velocity=0m/s

then, v=u+at

u=at

u=10*2

=20m/s
