a = v2 - v02 / 2 d = (3.52 - 0) / (2 * 2.5)
a = 2.45 m/s2
T = m (g - a)
= 3 (9.8 - 2.45) = 22.05 N
torque = I * alpha
T R = (1/2 M R2) * (a / R)
mass of cyclinder = 2 T / a
= 2 * 22.05 / 2.45
mass of cyclinder = 18 kg

A light string is wrapped around the outer rim of a hollow cylinder (ignore spokes) that can rotate without friction about an axle through its center. A 7 kg stone is tied to the free end of the string. When the system is released from rest, you determine that the stone accelerates downwards at a rate of 5.6 m/s 4. What is the tension in the string? a. 28.4 N b. 29.4 N ?. 39.2 N d. 68.6 N e....
A thin light string is wrapped around the outer rim of a uniform hollow cylinder
A thin lightstring is wrapped around the outer rim of a uniform hollow cylinder of mass 4.15kg (as shown in picture attached) having inner and outer radii as shown in thefigure . The cylinder is then released from rest.A)How far must the cylinder fall before its center is moving at 6.74m/s ?B)If you just dropped this cylinder without any string, how fast would its center be moving when it had fallen the distance in part A?C) Why do you get...
