    Ball throws upward, find maximum height

    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...

    Change in gravitational potential energy and work done against gravity

    My line of thought was that I would take the Gravitational Potential Energy and subtract the acceleration of gravity (9.81m/s^2). I don't think that it's right, that was just something I tried.

    What mass would be required to overcome static friction?

    Homework Statement The coefficient of static friction for wood on wood is 0.40, what mass would be required to overcome static friction of a 1.53 x 10^3 g block of wood on a wood table? Homework Equations I have absolutely no idea. The Attempt at a Solution I don't know. Thanks...
