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
