A water balloon with a mass of 500 g is launched across a waterpark and lands 150 m away 5 seconds later. What is the initial velocity in the x and y directions, launch angle, and max height?
The launch angle was approximately
Assume no air resistance and that the water balloon was launched at ground level.
Horizontal velocity =
We know that the balloon traveled 150 meters horizontally in 5 seconds so
The horizontal distance,
which implies that
The vertical height,
Use the last two equations to eliminate
The balloon lands when
The max height will be halfway through the flight or when
