Compute all parts of given problem:
Problem: A child throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. The ball leaves her hand 1.00 m above the ground and experience negligible air resistance.
Part A: How far from where the child is standing does the ball hit the ground?
Part B: How long is the ball in flight before it hits the ground?
I need help to find how far from where the child is standing does the ball hit the ground.
