A defense air force plane, diving with constant speed at an angle of `52.0^(@)` with the vertical, drops a shell at an altitude of 720 m. The shell reaches the ground 6.00 s after its release. (a) What is the speed of the plane? (b) How far does the shell travel horizontally during its flight? What are the ( c) horizontal and (d) vertical components of its velocity just before reaching the ground? Assume an x axis in the direction of the horizontal motion and an upward y axis.

Explanation

(a) 147 m/s, (b) 696 m, ( c) 116 m/s, (d) 149 m/s
