1. What is a given= 0.215 [ms^-2] and diameter of disk with uniform mass distribution= 19.5 [cm].

theta= ?

2. Using information found in previous question, if the dropping mass is 195 [g], then what is T?

T= ? [Nm]

Expert Solution

(a)

The acceleration is a = 0.215 m /s²

The radius of the disk is,

r = diameter / 2

= 19.5 cm /2

= 0.0975 m

Hence, the angular acceleration is,

? = a / r

= 0.215 m/s²/ 0.0975 m

= 2.205 rad/s²

---------------------------------------------------------------------------------------------------

(b)

The required tension can be calculated as,

T = m a

= 0.195 kg * 2.205 rad/s²

= 0.4299 N.m

= 0.43 N.m

A cockroach of mass m lies on the rim of a uniform disk of mass 4.00 m that can rotate freely about its center like a merry-go-round. Initially the cockroach and disk rotate together with an angular velocity of 0.230 rad/s. Then the cockroach walks half way to the center of the disk. What then is the angular velocity of the cockroach-disk system? What is the ratio K/K0 of the new kinetic energy of the system to its initial kinetic...

A frictionless pulley has the shape of a uniform solid disk of mass 6.00 kg and radius 12.0 cm . A 3.60 kg stone is attached to a very light wire that is wrapped around the rim of the pulley(Figure 1), and the stone is released from rest. As it falls down, the wire unwinds without stretching or slipping, causing the pulley to rotate. How far must the stone fall so that the pulley has 7.50 J of kinetic energy?

A uniform disk of radius 0.543 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with same mass as the disk\'s is attached around the disk\'s rim. A tangential force of 0.201 N applied at the rim causes an angular acceleration of 0.119 rad/s2. Find the mass of the disk.
