A projectile is fired with an initial speed of 65.8 m/s at an angle of 33.3? above the horizontal on a long flat firing range
a.) Determine the maximum height reached by the projectile.
b.) Determine the total time in the air.
c.) Determine the total horizontal distance covered (that is, the range).
d.) Determine the speed of the projectile 1.20s after firing.
e.) Determine the direction of the projectile 1.20s after firing.
