A projectile of mass 0.750 kg is shot straight up with an initial speed of 18.0 m/s. How high would it reach with no air resistance? What is the average force of the air exerted on it if the projectile reaches a max height of 11.8 with air resistance?

The force of the air resistance is
Explanation:
The loss in kinetic energy is
The initial velocity is
The final velocity is
The height is
There is a loss of potential energy due to air resistance
This is equal to the work done by the force of air resistance
The force of the air resistance is
