Next Problem
A projectile is fired from the ground (you can assume the
initial height is the same as the ground) in a field so there are
no obstacles in its way. It is fired at an angle of 37° with
respect to the horizontal and with an initial speed of 36 m/s.
Air resistance is negligible in this situation. Call up the
positive y direction, and toward the wall the positive x
direction.

The same projectile was then fired in the same way
toward a wall that is a horizontal distance 106.6 m
from where the projectile was fired. What was the
height of the projectile when it hit the wall?
hFinal =
A Linking Quantity
