A pizza is being dropped from a height of 20 m. Another pizza is being thrown up at 30m/s from 0m(the one falling is above the one being thrown). At what position in the air will they meet?
Im not sure but i think that some of the b5 kinematics equations would apply. Im pretty sure that this requires a simultaneous equation.
The Attempt at a Solution
first i had x=viT+1/2aT^2
i attempted to get all the t's to one side but got stuck at (2x/vi)/a=(t^2)/vi)+2t/a
i assumed that the t's must be equal. I am unsure whether or not i approached the problem correctly or not
