(use g = 9.8 ms^-2) <----gravity
From a point 120 meters above ground level a stone is projected vertically upwards with a speed of 'u' ms^-1. If the stone rises to a height of 5 meteres abv its point of projection calculate:
(a) value of u
(b) time taken by the stone from being projected untill it reaches ground lvl
(c) speed of stone at the instant that it hits the ground
can u guys explain and show me how to do these questions?
