Name Avery giese Central Net Force Model Worksheet 2: Date S-20-24 Pd4 Radial Net Force 1. / a. A car travels through a valley at constant speed, though not at constant velocity. Explain how this is possible. c, Is the car accelerating? What direction is the car's acceleration? (Explain how you know.) d. Construct a qualitative force diagram for the car at the moment it is at the bottom of the valley. Are the forces balanced? Justify the relative sizes of the forces. e. If the car's speed is 25 m/s, its mass is 1200 kg and the radius of valley (r) is 25 meters, determine the magnitude of the centripetal force acting on the car. f. Construct a quantitative force diagram for the car at the bottom of the valley. Modeling Instruction - AMTA 2013 U7 Central Force Model - ws2 v3.1
