Question
A ball thrown up vertically returns to the thrower after 6 s. (a) the velocity with which it was thrown up. (b) the maximum height it reaches, and (c) its position after 4 s.
Solution
(a) The velocity with which it was thrown up.
We know that the total time of flight for a projectile thrown upwards is given by the formula t = 2u/g, where u is the initial velocity and g is the acceleration due to gravity.
Given that t
