You are given the following data about a golf club hitting a stationary golf ball: mass of club head = 0.350 kg
mass of golf ball = 0.046 kg
speed of club head before collision = 38 m/s
speed of club head after collision = 29 m/s
Calculate the following:

collision
B. momentum of club head after
collision
C. momentum of golf ball before
collision
D. momentum of golf ball after
collision
E. speed of the golf ball after it is
hit by the golf club ___

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

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?
