A ball is thrown vertically upwards.It takes 4 s for the ball to return to the thrower's hand now what is thb maximum height reached by the ball.

Anonymous,
you need more information to solve the problem, such as the initial or final velocity.
If you have this information you can solve for d (displacement) using the equation (s):
 Vf^2= Vi^2 + 2*g*d where g is the acceleration due to gravity (9.8 m/s^2)
 d= Vi*T+0.5*gT^2 where t is time
Hope this helps
