Ball throws upward, find maximum height

[Amber3046]

Homework Statement

You throw a ball directly upward giving the ball an initial velocity of 10m/s. Neglecting friction, what would be the maximum height of the ball? (Explain why you do not need to know the mass of the ball)

Homework Equations

not sure

The Attempt at a Solution

vi=10m/s d=?
not much of an attempt, i know

 

[SbCl3]

The ball has an initial kinetic energy, which is transformed into an increase in gravitational potential energy.

Max height occurs when v_y equals zero.

so if v1 = 10 m/s , think wut would the speed be at maximum height , and remember there is always the acceleration of gravity [ down ] acting on all object thrown upward!
