Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. F(N) Students collect data, see graph, for the force involved in stretching a 12 rubber band. The data is well fit by the equation F = 33.65 x0.4971, 10 where F is in newtons and x is in meters. One end of the rubber band is attached to a stationary vertical rod and the other end to a 0.3 kg mass. The mass rests on a frictionless horizontal surface. The mass is 4 pulled back such that the rubber band is stretched by 0.8 m from its unstretched length and then released from rest. 2. X (m) 0,1 0.02 0.04 0.06 0.08 A. What is the speed of the mass after it has traveled 0.4 m? B. What is the maximum speed of the object?
