Question

an artillery piece is pionted upward at an angle of 35degree with respect to the horizontal and fire a projectile with a muzzle velocity 200meter per second .if air resistance is negligible to what height will the projectile rise.

Answer 1

Vo = 200m/s[35o].
Yo = 200*sin35 = 114.7 m/s.

Y^2 = Yo^2 + 2g*h.
Y = 0.
g = -9.8 m/s^2.
h = ?

Answer 2

h=vo2sin2theta\2g
h=(200)2*sin 2 35\19.6
h=40000*0.36\19.6
h=672.4
