Question

A dragster is speeding down the track at 150 m/s. Its rear wheels are 2 m in diameter, and its front
wheels are 40 cm in diameter. What are the angular velocities of the front and rear wheels, respectively?

Answer 1

At what angle is a force directed if its horizontal component is 10 N and the vertical component is 15 N?

Answer 2

omega r = v
r in meters
v in meters/sec
omega in radians/sec

rear
omega * 1 = 150

front
omega * 0.20 = 150

tan theta = y component / x component = 1.5
tan^-1 (1.5)
56.3 degrees above horizontal
