Transverse waves with a speed of 59.0 m/s are to be produced on a stretched string. A 4.95-m length of string with a total mass of 0.0600 kg is used. (a) What is the required tension in the string? N (b) Calculate the wave speed in the string if t..
A 40.0 ball of clay travelling east at 6.00 collides and sticks together with a 20.0 ball of clay travelling north at 5.00. What is the speed of the resulting ball of clay.
Four particles, one at each of the four corners of a square with 3m-long edges, are connected by massless rods. The masses of the particles are m1 = m3 = 4kg and m2 = m4 = 5kg. Determine the moment of inertia of the system about the z axis.
A 2.5kg mass is attached to a spring and placed on the horizontal, smooth surface. A horizontal force of 18.4 N is necessary to hold the mass at rest while it is pulled 0.210 m from its equilibrium position.
An alert physics student stands beside the tracks as a train rolls slowly past. He notes that the frequency of the train whistle is 445 Hz when the train is approaching him and 418 Hz when the train is receding from him. Using these frequencies, h..
