A cannon ball is fired from Castle ramparts which are 24.5 m above ground leve. It is fired at an upwards angle of 30⁰ and the muzzle velocity is 39.2ms‐¹.

Calculate the vertical component of the velocity as the cannon ball hits the ground?

The initial velocity in the vertical direction can be calculated by using the angle of trajectory (create a triangle). You have the acceleration which is simply g (9.8ms^-2), you also have the distance travelled in terms of vertical displacement (which in the upwards direction would be -24.5) ensure that all values have the correct sign and use the appropriate equation to find V.

V2 - U2 = 2as
