Adisc rotates at a constant angular speed. the turn around time (t) is 0.5 seconds.
a point x of the disc is located at a distance of 20 cm from the center.
a: calculate the speed of the disc
b: calculate the web speed of x
c: calculate the angular speed of the disc
d: calculate the midpoint angle over which the disc rotates in 4 seconds.
e: calculate the path that the point x travels in 4 seconds.
can someone solve this
