Question

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.

Answer 1

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
