Q1. Driving in your car with a constant speed of 12.0 {rm m}/{rm s}, you encounter a bump in the road that has a circular cross-section. If the radius of curvature of bump is 35 {rm m}, find the apparent weight of a 69 person in the car as you pass over the top of the bump.

Q2. The heating coil of a hot-water heater has a resistance of 20.0 and operates at 210 V. If electrical energy costs $0.080/kWh, what does it cost to raise 290 kg of water in the tank from 15 °C to 74° C?
