You toss a ball from your window and hit the ground. Ignore air resistance, and g = 9.80 m/s2. When the ball leaves your hand, it is moving at 10.0 m/s at an angle of 20o below the horizontal. It is found that the ball hits the ground 18.4 m horizontally from your window. (1) What are the x-component (Vx0) and y-component (Vy0) of the initial velocity? (2) When the ball will hit the ground (give the time (t))? (3) How high (in meter) is it from your window to the ground?

(1) What are the x-component (Vx0) and y-component (Vy0) of the initial velocity?
(2) When the ball will hit the ground (give the time (t))?
(3) How high (in meter) is it from your window to the ground?
4) What is the final x-component (Vxf) and y-component (Vyf) velocity of the ball when it hits the ground?
(5) What is the final speed of the ball when it just hits the ground?
u= 10m/s with 20° below the horizontal
X= 18.4m
