A toy top with a spool of diameter

Reference no: EM13553019

A toy top with a spool of diameter 5.0 cm has a moment of inertia of 3.0 X 10^5 kgm2 about its rotation axis. To get the top spinning, its string is pulled with a tension of 0.30 N. How long does it take for the top to complete its first five revolutions? The string is long enough that it is wrapped around the top more than five times.
