While a vehicle with a mass of 2350 kg is moving at 120 km/h, suddenly braking It stops with an acceleration of -9.18 m/s2. There are two brake pads on each wheel of the vehicle. The friction coefficient between the brake pad and the brake disc is 0.3. During braking, assume 20 N/mm2 is the pressure on the brakke pad, find the area of the pad. Safety coefficient will be taken as 3

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
