A tightrope walker begins crossing a rope at t = 0 s and walks at a speed of 1.0 m/s as shown below. After 12.0 s, a large bird lands on the far end of the rope and the acrobat stops walking. The bird causes a transverse wave pulse to move along the rope, toward the acrobat. If the rope has a tension of 3.00 kN, a mass of 10.0 kg and is 30.0 m long, how long after the...

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...
