Question

An artillery shell is fired at an angle of 83.3 ◦ above the horizontal ground with an initial speed of 1600 m/s. the acceleration of gravity is 9.8 m/s 2 . find the total time of flight of the shell, neglecting air resistance. answer in units of min. 002 (part 2 of 2) 10.0 points find its horizontal range, neglecting air resistance. answer in units of km.

Answer 1

T = 2*V₀*sin (α) / g .

t = 2*1600*sin (83.3°) / 9.8 ≈ 2*1600*0.993 / 9.8 ≈ 324 sec   or  5.3 min
