A mass-spring system oscillates with an amplitude of 5.50cm. If the spring constant is 247N/m and the mass is 584g,determine,
a. the mechanical energy of the system
b. maximum speed of the object
c. maximum acceleration
Two cylindrical rods are identical, except that one has a thermal conductivity k1 and the other has a thermal conductivity k2. As the drawing shows.
One hundred k mol of a gas containing 94.4 mole% methane, 3.40% ethane, 0.60% propane, and 0.50 percent butane is to be burned with 17% excess air. Calculate the required molar flow rate of the air.
