Homework Statement
A rock is shot straight up from a slingshot with an initial speed of 30 m/s. When it's exactly halfway to the top of its flight, a second rock is shot straight up from the same spot. The second rock reaches the first rock just as the first rock reaches its apex (highest point).
1.What is the "muzzle" speed of the second rock? (The muzzle speed is the speed at which the rock leaves the sling shot.)
2.What maximum height does the second rock reach?
The Attempt at a Solution
I don't even know where to start :S
Please help!
thanks :)
