Question

Two angles are complementary when their sum is 90.0°.
Find the ranges for two projectiles launched with identical initial speeds of 36.2 m/s at angles of elevation above the horizontal that are complementary pairs.
(a) For one trial, the angles of elevation are 36.0°and 54.0°.
(b) For the second trial, the angles of elevation are 23.0°and 67.0°.
(c) Finally, the angles of elevation are both set to 45.0°.
(d) What do you notice about the range values for each complementary pair of angles? At which of these angles was the range greatest?
