A bungee cord is stretched between two poles 498 meters apart and it has a mass of 370.2 grams. If the force needed to stretch the bungee cord is 370 N, what is the velocity of a wave on this bungee cord?
A basketball player is standing on the floor 10.0 m from the basket. The height of the basket is H = 3.05 m, and he shoots the ball at an angle, ? = 36.4°, with the horizontal from a height of h = 1.82 m.
A heavy pole, of mass M and length L, is freely hinged to a wall at the point 0. A rope connects the other end of the pole, B, to a fixed point A on the wall above 0. The system is in equilibrium, with the pole making an angle θ with the horizonta..
A steel wire in a piano has a length of 0.8000 m and a mass of 3.900 10-3 kg. To what tension must this wire be stretched so that the fundamental vibration corresponds to middle C (fC = 261.6 Hz on the chromatic musical scale)?
A square loop of wire consisting of a single turn is perpendicular to a uniform magnetic field. The square loop is then re-formed into a circular loop, which also consists of a single turn and is also perpendicular to the same magnetic field. What is..
