Homework Help: Physics

Posted by Katie on Monday, June 18, 2012 at 5:12pm.

At time t = 0, you shoot a cannonball horizontally from the roof of a building at a velocity of 10 m/s. The building has a height of 80 m. Assume g = 10 m/s2 and that there is no air resistance.

Write down the algebraic velocity equation for the y-direction of the ball with any given values substituted.

Write down the algebraic position equation for the y-direction of the ball with any given values substituted.

So I need to equations for vertical velocity (Vy) and vertical position (y)
