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?

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

because if the tool that you are using is not balanced it there would be false mass.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
