A projectile is fired with an initial speed of 150 m/s and angle of elevation 60∘. The projectile is fired from a position 100 m above the ground. (Use g = 9.8 m/s2. Round your answers to the nearest whole number.) (a) Find the range (in m ) of the projectile. m (b) Find the maximum height (in m) reached. m (c) Find the speed (in m/s) at impact. m/s
