Problem

An object is launched from the ground at an angle of 60° above the horizontal with a speed of 20.0 ms\frac{m}{s}. What is the magnitude of the average velocity of the object from just after launch until it reaches its highest vertical position during flight? (A) 13.7 ms\frac{m}{s} (B) 13.2 ms\frac{m}{s} (C) 10.0 ms\frac{m}{s} (D) 9.3 ms\frac{m}{s} (E) 8.7 ms\frac{m}{s}
