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.
