Chapter 5 Assignment 1. A 1500kg safe is being dragged by a tow truck. The truck pulls the safe with a force of 2500N. If the coefficient of kinetic friction is 0.014, then find the speed of the tow truck and the safe after 5.0 seconds. Start by drawing a FBD. 2. You push a 50.0 kg box across a floor at a constant speed of 2.0m/s. If the coefficient of friction between the two surfaces is 0.20, then how much force are you exerting on the box? If you stop pushing, then how far will the box slide before coming to rest? Start by drawing a FBD. 3. Blocks with masses of 1kg, 2kg and 3kg are lined up in a row on a frictionless table. All three are pushed forward by a 12N force being applied to the 1kg box. a. Draw FBDs for all 3 individual boxes. b. Find the acceleration of the system. c. Find the force the 2kg block applies on the 3kg block. d. Find the force the 2kg block applies on the 1kg block. 4. A steel rod with a handle is attached to a 35 kg block. A 300.0 N force is applied to pull the block across the room. This force causes the block to reach a speed of 4.0m/s as it travels a distance of 2.0 m. If the coefficient of friction between the two surfaces is 0.30, then what is the mass of the attached rod? Start by drawing a FBD. hp 9%
