Question
You can use any coordinate system you like in order to solve a projectile motion problem. To demonstrate the truth of this
statement, consider a ball thrown off the top of a building with a velocity v at an angle 0 with respect to the horizontal. Let the
building be 54.0 m tall, the initial horizontal velocity be 9.10 m/s, and the initial vertical velocity be 10.5 m/s. Choose your
coordinates such that the positive y-axis is upward, and the x-axis is to the right, and the origin is at the point where the ball is
released.
(a) With these choices, find the ball's maximum height above the ground and the time it takes to reach the maximum
height.
maximum height above ground
time to reach maximum height
(b) Repeat your calculations choosing the origin at the base of the building.
maximum height above ground
time to reach maximum height
