1. The problem statement, all variables and given/known data A child sitting in a tree throws an apple core from where he is perched (4 m high) with a velocity of 5 m/s [35 degrees above horizontal] and it hits the ground next to his friend. How long before the core hits the ground? 2. Relevant equations dy = vy(initial)t + 1/2at quadratic eqn. 3. The attempt at a solution Would I calculate the x-y components of the initial velocity then plug in the initial y velocity to the first aforementioned eqn then solve for t using the latter eqn?
