A problem from Projectile motion

If maximum height attained by a body projected vertically upward is equal to two times magnitude of acceleration , then its time of flight is ………. ? (Divya posted) Answer: If you take g=10 m/s2 then H=20m At max height, v=0 H=vt- 0.5 g t2 t=√(2 x 20/10)=2s This is the time taken to reach max height. […]
