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....

A question from Kinematics.

An object thrown vertically up from the ground passes the height 5m twice in an interval of 10s. What is its time of flight? (Divya asked) Answer: The question seems partial. I am assuming that g= 10 m/s2 and the projection is strictly vertical. The o...
