In this section we need to look at the particle as it lands !

A particle lands when Sy = 0,

So how could we find the angle that the projectile lands ?

We can find the angle by finding the velocity (in x & y) of the projectile at the time that Sy = 0.

So like in the previous section we need to find the time that Sy = 0

then put this time in for the velocity of the projectile in both planes

so we need the formula for Vx and Vy and put the time in

then the angle can be found

what about if the particle strikes the plane at right angles to the inclined plane ?
