Athin rope with a linear density of 2.22 g/m is attached to a thick rope with a linear density 15.19 g/m. they support a 8.11 kg mass which is suspended from a massless pulley at the end of the thick rope. a sinusoidal pulse with amplitude 6.81 cm is sent along the thin rope.
a)what is the speed of the pulse along the thin rope?

b)half the power is transmitted and half is reflected at the boundary of the thin and thick ropes. what is the amplitude of the reflected pulse?

c)what is the amplitude of the transmitted pulse?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
