A 56-kg student runs at 6.0 ms, grabs a hanging 10.0-m-long rope, and swings out over a lake (Fig. 6–50). He releases the rope when his velocity is zero. (a) What is the angle u when he releases the rope? (b) What is the tension in the rope just before he releases it? (c) What is the maxi- mum tension in the rope during the swing?

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.
