A cannon ball is fired at an angle 30 degrees from horizontal from a cannon with a speed 30km/h, a) calculate how high the cannonball flies, and the horizontal distance from the cannon the cannonball reaches

convert 30km/h = 8.3 m/s

calculate initial vertical speed U= 4.15m/s, calculate initial horizontal speed = 7.19m/s

apply suvat equations v = u + at, s = ut + 1/2atand solve for t, s

final answers shorizontal = 5.97m, svertical = 0.86m
