Question

1. A bullet is fired from gun mounted at an angle of 30°. If the muzzle velocity is

400 m/s, calculate:

a. Vertical velocity component

b. Horizontal velocity component

c. Maximum height reach

d. Time of flight

e. Range

p.s.with calculation if possible please, thank you, sir:)

Answer 1

$$v_y=400\sin{30}-9.8t\\v_x=400\cos{30}=\frac{m}{s}\\H=\frac{400^2\sin^2{30}}{2(9.8)}=2041\ m\\\\t=2\frac{400\sin{30}}{(9.8)}=40.8\ s\\\\R=\frac{400^2\sin{60}}{(9.8)}=14139\ m\\$$
