A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28 degree incline. After sliding down the 110-m long include (on which the coefficient of kinetic friction is u_k = 0.18), the snowboarder has attained a velocity V. The snowboarder then slides along a flat surface (on which u_k = 0.15) and comes to rest after a distance x.
Use Newton's second law to find the snowboarder's acceleration while on the incline and while on the flat surface.
A_incline = ?
A_flat = ?
Then use these accelerations to determine x.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
