Afather and his daughter are standing on a sheet of ice, facing each other. their arms are held straight out in front of them, palms touching. another ice-skater trips and bumps into the daughter, applying a force of 900 n to her back. the two begin to move. if the father weighs 250 lb and the daughter weighs 70 lb, what is the magnitude of the force that the father exerts on the daughter, while they are accelerating? answer in n. (1 lb = 4.45 n)
