A Toy Top With A Spool Of Diameter

How long will it take to complete the first five laps in the top? 3

The strap is long enough to wrap the heads in more than five turns.

A top toy with a diameter of 5.0 cm connects 2.5 × 10 × 5 kgm

r = 0.025 m

I = 2.5x10 5 kgm2

A constant force is applied.

Pair = IÃÂ

0.32 x 0.025 = 2.5 x 10 5

± = 320 rad / s²

The starting angle is sd z because the top must be rotated.

w = ± t

¸ = ½Î ± t²

¸ = S / r = (5x2 r) / (r) = 10Â

€ 10 = (320) t²

t = 0.443 seconds
