Question

An object of mass 50g thrown against Earth gravity with a velocity of 25m/s. Find :-
(i) the time taken to reach the maximum height
(ii) the maximum height
(iii) the velocity with which it fall at ground​

Answer 1

Time taken to reach max height = u/g = 25/10 = 2.5sec

max ht = $u^{2} /2g$ = 625/20 = 31.25m

vel with wich it reach ground = 25m/s
