# A projectile of mass 0.750 kg is shot straight up with an initial speed of 18.0 m/s.

A projectile of mass 0.750 kg is shot straight up with an initial speed of 18.0 m/s.

**Part a)** How high would it go if there no air resistance? *(3 points)*

**Part b)** If the projectile rises to a maximum height of only 11.8 m, determine the magnitude of the average force due to air resistance. *(3 points)*

**Part c)** If the speed of the projectile is doubled in part a, by what factor would the height change by? Justify. *(3 points)*
