1. The problem statement, all variables and given/known data In this Lab you will toss water balloons over the edge of a raised sidewalk. The thrower should hold the balloon over the edge of the sidewalk and then toss it directly upward. As soon as the balloon is released the person on the ground should start the timer. Stop the timer when the balloon hits the ground. Balloon is released at 6.2m above ground and lands in 2 seconds. What is the initial velocity, final velocity and maximum height of travel? 2. Relevant equations v=at+Vo y-y=Vot + 1/2at^2 3. The attempt at a solution Tried to solve for Vo and y by substitution and I keep getting zero!
