Homework Statement
A ball, thrown upward, leaves the thrower's hand at a height of 0.8m with a velocity of 5m/s.
How fast is the ball moving just before it hits the ground? (assume the thrower moves out of the way)?
Homework Equations
Could someone check my work to make sure I have the correct answer to the problem? Thanks very much in advance. Note that my answer is a negative number. That doesn't seem right to me.
The Attempt at a Solution
How fast is the ball moving just before it hits the ground?[/B]
v = u + at
I calculated time as being 1.16
v= 5 + (-9.8)(1.16) = - 6.37
final velocity is - 6.37
