a. Car A experiences a force that rises uniformly from 0 to 10 kN in 0.020 s and then falls uniformly back to zero in the next 0.030 s. Find the total impulse on the car during the entire 0.050 s interval.
b. Car B experiences a triangular force pulse that rises uniformly from 0 to 8 kN in 0.020 s and then falls uniformly back to zero in the next 0.020 s. Find the total impulse on the car during the 0.040 s interval.
c. Which car undergoes the greater change in momentum? State your answer with a short justification.
