An elastic powered car is pulled back, stretching the elastic by 0.6m. The elastic has a spring constant of 1.5 N/m. The car has a mass of 0.75 kg. Find the velocity the car travels at

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
