A house painter stands 3.00 m above the ground on a 5.00-m-long ladder that leans against the wall at a point 4.70 m above the ground. The painter weighs (6.60x10^2) N and the ladder weighs (1.900x10^2) N. Assuming no friction between the house and the upper end of the ladder, find the force of friction, in units of N, that the driveway exerts on the bottom of the ladder. Give your answer with three significant figures.
