Question

A uniform ladder XY of length 500cm and a mass of 20kg is placed against a smooth vertical wall with end Y uppermost and end X on a rough horizontal ground. The end Y is 400cm above the ground and the end X is 300cm out from the foot of the wall.If a girl of mass 70kg stand on a ladder at a point 300cm above the group ,what is the reaction force at the wall? and the magnitude of the reaction force at the ground and angle of this reaction force to the horizontal
Answer
Ok pls what should I put
A uniform ladder XY of length 500m long and mass 20kg is place against a smooth vertical wall with end Y upper most and end X on a rough horizontal ground, the end Y is 400m above ground and the end X is 300cm out from the foot of the wall. If a girl of mass 70kg stands on the ladder at a point 300cm above the ground, what is the reaction force at wall? the magnitude of the reaction force at the ground and angle of this reaction force and horizontal?
