An 80 kg person stands 0.75 m from the bottom of a ladder (i. e. d = 0.75 m). the ladder leans against a frictionless wall at a 60° angle. if the ladder is 50 kg and is 2.5 m long what is the friction due to the floor, in newtons, on the ladder?

the ladder in the previous problem had a person standing on it. assume this person climbs up so that he stands 2.0 m from the bottom of a ladder (i. e. d = 2.0 m). what is the force exerted by the wall, in newtons, on the ladder?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
