[pascho]

what is the range of this projectile?

 

[kony]

the displacement is 50.

therefore, 50 = (1/2)(9.8)t^2

work out t.

then use range = Ux * t.

what if the cannon ball is shot in an angle of 45 degree

 

[airie]

Just replace u_y with 60*cos45 degrees = 30rt2 m/s, and u_x 60*sin45 degrees = 30rt2 m/s. Then calculate as kony pointed out.
