A bike travels at 3.0 m/s, and then accelerates to a speed of 8.5 m/s in a time of 2.5 seconds. The fyerage acceleration of the bike is
m/s2

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

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.
