a mass m is attached to a string of length l and released when the string is horizontal, causing the mass to fall in a circular path. At the time that the mass has fallen through the angle ø, determine the following in terms of m, l, g, and ø:
a) the speed of the object
b) the maginitude of the centripetal acceleration
c) the magnitude of the tangental acceleration
d) the magnitude of the tension force
e) the maximum value of the tension force in the string
The 4 block in the figure is attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended and the tension in the upper string is 77.
The equation of a transverse wave traveling in a string is given by y=A sin(k x??t). The tension in the string is 18.0 N, A = 1 mm, k = 22 rad/m, ? = 325 rad/s. What is the linear density of the string. I have the speed of the wave but i cant get ..
