Show the weight of the ladder and draw the missing frictional force.

Since there is no friction between the ladder and the wall, there can be no vertical force component. That's the tricky part ;)

So to find the weight, divide the 100N normal force by earths gravitational acceleration, 9.8m/s^2



Then;
Draw an arrow at the base of the ladder pointing towards the wall with a value of 30N, to show the frictional force.
