Q. A trapeze artist swings in simple harmonic motion with a period of 3.7 s. Calculate the length of the calbes supporting the trapeze.
The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 2.2 m2, while surface 2 has an area of 3.5 m2.
For the Atwood's machine, suppose the masses have an initial speed of v = 0.22 m/s and that m2 is moving upward. How high does m2 rise above its initial position before momentarily coming to rest, given that m1 = 3.5 kg and m2 = 3.1 kg.
A 253 kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal.
A 3.9 kg block originally at rest is pulled to the right along a horizontal, frictionless surface by a constant, horizontal force of 18 N.
A kayaker needs to paddle north across an 85 m wide harbor. The tide is going out, creating a tidal current that flows to the east at 1.7 m/s. The kayaker can paddle with the speed of 3.0 m/s.
