A child kicks a ball from the ground level with initial speed Vo at an angle theta above the horizontal. the ball hits the ground 4 seconds later and the velocity at the maximum height is 10 m/s.
a) Calculate the ball initial speed Vo (Hint calculate Vox and Voy.)
b) Calculate the angle theta. Calc. Vox and Voy.
c) What is the maximum height the ball reaches?
d) How far away does the ball hit the ground.
