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?

A tall rectangular cabinet with two "feet" has a mass of 38.5kg. It is pushed using a horizontal force of 111N. If the force is applied at a height of greater than 1.05m above the ground, the cabinet begins to tip over. The width of the cabinet (distance between the 2 feet) is m. LL F > N₁ CM N₂ mg
A 9 m long board that has a mass of 14. Each end is held up by a vertical rope. A 45 kg box sits 1 m from the left end. Find the tension in the rope on the right. Hint: With forces applied at different places, this is a beam problem pick a pivot point measure all distances from the pivot point Apply Στ = 0 Don't forget torque = force x dist, so you need to multiply the masses by g = 9.8 m/s2 If you need more information, apply ΣF = 0
