Homework for period 1,3,5: Solve the three problems from class using the equations
H = -16t2 + vt + c
Where v = initial velocity
c = starting height
H = H(t), the height we care about at our point of interest
Period 2,4: Finish the Pythagorean worksheet, both sides.
The three problems
1) If a rock is dropped off a bridge that is 30 feet above a
river, how long will it take for the rock to hit the water?
2) A tennis player hits a ball 1 foot above the ground with
an initial velocity of 20 feet per second. How long will it
take to hit the ground?
3) You drop a water balloon off a building 200 feet in the air. How long until it hits your friends head who is 6 feet tall?
