(a)One end of a string is attached to a wall and the other end is attached to a mass sitting on a ramp tilted at an angle of 35 degrees. It takes a pulse 10 ms to travel the length of the 1 m string. The string has a mass 1.5 g. What is the mass that is attached to the string?

 

(b) The string is replaced by two strings that are knotted together, L1 has a length 60 cm and L2 has a length of 40 cm. They have a linear mass density of of mu1 = 1.4 x 10-4 kg/m and mu2 = 2.8 x 10-4 kg/m. Like before, they are attached to the mass you found in part a. A pulse is sent from each end of the string. Which pulse meets the knot first?

From the end of a string (whose other end is firmly attached to the ceiling) we attach a mass m1.Similarly, we attach a mass m2 from the end of a different string. Both strings have equal lengths and the masses are barely in contact when they are hanging freely. We pull out both masses so that they form angles θ1and θ2, respectively, with their equilibrium (vertical) positions. We then release the masses such that there is an elastic, heads-on collision...

A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.6 kg and 2.3 kg, and the length of the wire is 1.21 m....
