Mr. Smith is on top of a building launching water balloons. Let's assume he is 15 m above the ground and he is launching them at an angle of 30o above the horizon with a speed of 20 m/s.
A) Obtain the horizontal and vertical components of the velocity of the balloons at the moment of launch?
B) Find the maximum height above the ground the balloons will reach?
C) Compute how long will the balloons be in the air?
D) Evaluate the horizontal range of the balloons?
