The Jetta is Volkswagen's best-selling car in the United States. Multiple Choice Questions 1) A Jetta travels at 33 m/s. Assuming the 21 cm-radius wheels roll without slipping, how many revolutions do they make every minute? a) 500 rpm b) 700 rpm c) 900 rpm d) 1100 rpm e) 1300 rpm f) 1500 rpm 2) The Jetta's radiator removes excess thermal energy. If the radiator has a temperature of 95 °C, an emissivity of 0.9, and a surface area of 1.1 m², what power does it radiate? a) 1 kW b) 2 kW Short Answer Question c) 3 kW d) 4 kW e) 5 kW f) 6 kW The Jetta has a mass of 1500 kg and it accelerates from rest to its final speed over the course of 20 s. The net force (in N) for this time interval is given by Frer(t) = 22.512-80t + 790, where t goes from 0 to 20 s. ⚫ Draw a motion diagram for this Jetta as it accelerates from rest. ⚫ What is the impulse (in kg m/s) over these 20 s? ⚫ What is the final speed (in m/s) of the Jetta after 20 s? . What is the average net force (in M) on the Jetta?
