A projectile is fired with an initial speed of 61.3m/s at an angle of 44.2∘ 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 1.15s after firing.
Help! I have no idea where to begin or how to solve. Please explain!
