A car accelerates from rest to a maximum speed of 20 m/s over a 20 s time interval. The net force on the car as function of time is given by Fnet = 3350 (t + 1)-1/2 where Fnet is measured in N and t goes from 0 to 20 s. Multiple Choice Questions 7) What is the impulse on the car as it accelerates from rest to its top speed? a) 1.8 × 104 N. S b) 2.4 x 104 N.S c) 3.8 × 104 N s d) 4.1 x 104 N s e) 5.8 × 104 N. s f) 8.5 × 104 N. S 8) Assume that the wheels on the car each have a diameter of 49 cm and that the outside edge of the wheel spins with a tangential velocity of 20 m/s. If each of the wheels has a moment of inertia I = 0.75 kg. m², how much rotational kinetic energy does a single wheel have while traveling at this speed? a) O J b) 120 J c) 478 J d) 1913 J e) 2499 J f) 7653 J
