Q1. The sound intensity level at a rock concert is 103dB, while that at a jazz fest is 72.30 dB. Determine the ratio of the sound intensity at rock concert to that at the jazz fest.
Q2. Suppose an 1800 kg car passes over a bump in a roadway that follows the arc of a circle of radius 20.0 m as in the figure shown below. (a) What force does the road exert on car as the car passes the highest point of the bump if the car travels at 8.34m/s? (Avoid any friction that may occur.) Magnitude your response differs from the accurate answer by more than 10%. Double check the calculations. N direction (b) what is the maximum speed car can have without losing contact with road as it passes this highest point?
