Question

A stone is thrown in a vartical upward direction with a velocity of 5m/s.if the acceleration of the stone during it's motion is 10m/s2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach their.

Answer 1

height = u²/2g = 5²/2×10 = 25/20= 5/4 = 1.25m

time = 2u/g = (2×5)/10 = 1s
