1. time to blue max ... v / g
red vel @ blu max ... v - g t
ave red vel ... (2 v - g t) / 2
red hgt ... (ave vel) * t
2. blu ... time up = time down
red vel @ blu impact
... v - g(blu flight time)
A red ball is thrown directly upwards from the ground with an initial velocity of 35.0 m/s. At the same time, a blue ball is thrown directly upwards from he ground with an initial velocity of 10.0 m/s.
1. How high is the red ball when the blue ball reaches its highest point?
2. How fast is the red ball travelling when the blue ball hits the ground?
