A shell is fired from the ground with an initial speed of 1.68 103 m/s at an initial angle of 37° to the horizontal.
(a) Neglecting air resistance, find the shell's horizontal range.
(b) Find the amount of time the shell is in motion.

  • Physics -

    time in air:

    vertical speed initial: 1.68E3 sin 37
    hf=hi+Vi*t-1/2 g t^2
    0=0+1.68E3 sin 37 *t-4.8t^2
    solve for time of flight, t.

    horizontal range:
    distance= 1.68E3*cos37*t
