5. A 0.2 N force is exerted on thread wrapped around a spool which is allowed to rotate freely about its center. The thread is pulled tangentially to the inner part of the spool (diameter 3 cm) for 3 seconds, while the whole spool (diameter 2 cm, moment of inertia 2 x 10-5 kg.m²), initially at rest, starts to rotate. A) What is the angular acceleration of the spool as the thread is pulled? B) After the 3 seconds, what is the angular speed of the spool? C) How many radians has it rotated in this 3 second interval? 2 cm cm 0.2 N

A shaft is rotating at a uniform speed with four masses m1, m2, m3 and m4 of magnitudes 300 kg, 450kg, 360kg and 390 kg respectively. The masses are rotating in the same plane. The corresponding radii of rotation are 200mm, 150mm, 250mm and 300mm. The angles made by these masses with respect to horizontal are 0°, 45°, 120° and 255° respectively. 1) Check the magnitude and position of balance mass if it radius of rotation is 200mm, and 2) Evaluate the effect of adding the balance mass to the system. solve it using garphical method

Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. a. How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
