Question

A particle P is projected vertically upward from a point in 6 seconds later and the particle Q is projected vertically upward from point a both P and Q reach A7 10 asleep the ratio of maximum height reached by p and q = 64:25 find the velocity of the projection of you in m/s

Answer 1

Time taken will be time of ascent given by u/g

Where u is intial velocity and g is acceleration due to gravity

So T=10/9.8=1.02 seconds
