STOPPING DISTANCE QUESTIONS You have a heavy duty paper clip of mass m = 0.010 kg. You slide it across the table, initially at speed V; 2.5 m/s. This table top produces a friction force f = 0.019 N on the sliding paper clip. STOPPING DISTANCE CALCULATION (3 points) Calculate the stopping distance of this paper clip. Type in to the nearest 0.01 m. E.g., if your stopping distance is 2.448 m, then type in 2.45.

4. It takes 4.186 joules of energy to heat up 1.00 grams of water by 1 K. You expose 100.0 mL of pure water to radiation that has a wavelength of 113 pm. If that sample of water starts at 20.0 °C how many moles of photons need to hit the water before it reaches 100.0°C? Assume that the density of the water is 1.00 g/mL.
