A projectile is fired with an initial speed

of 46.6 m/s at an angle of 42.2° above the horizontal on a long flat firing

range. Determine (a) the maximum height reached by the projectile, (b) the

total time in the air, (c) the total horizontal distance covered (that is, the

range), and (d) the velocity of the projectile 1.50 s after firing.
