Question: William is shooting at an apple that hangs on a tree. The apple is a horizontal distance of 20.0m away and at a height of 4.00m above the ground.
Part A: If the arrow is released from a height of 1.00m above the ground and hits the apple 0.580s later, what is the arrow's initial velocity?
Please show all intermediate steps and formulas for above question.
