Question

A projectile is fired with an initial speed of 180 m/s and angle
of elevation 60°. The projectile is fired from a position 110 m
above the ground. (Recall *g* ≈ 9.8 m/s^{2}. Round
your answers to the nearest whole number.)

(a) Find the range of the projectile.

m

(b) Find the maximum height reached.

m

(c) Find the speed at impact.

m/s
