Q. A skier attained a speed of 15 m/s down a slope with a 40 degree incline. It took the sled rider 4 seconds to achieve such a speed after she started down the slope. Determine the coefficient of kinetic friction between sled and snow.

Q. A thermometer has a mass of 31-g, a specific heat capacity of C=815J/(kg.C degrees) and a temperature of 12.0 degrees celsius. It is immersed in 119 g of water and the final temperature of the water and thermometer is 41.5 degrees celsius. What was the temperature of the water before the insertion of the thermometer?
