In the figure here, a cylinder having a mass of 2.8 kg can rotate about its central axis through point O. Forces are applied as shown: F1= 9.7 N, F2 = 8.3 N, F3 = 1.8 N, and F4 = 4.5 N. Also, r = 4.3 cm and R = 10 cm. Taking the clockwise direction to be negative, find the angular acceleration of the cylinder. (During the rotation, the forces maintain their same angles relative to the cylinder.) %3D Rotation axis Number Unit

Hello, I need help with physics. Thank you!Calculate the rotational inertia of a solid, uniform sphere with a mass of 12.2 kg and a radius of 0.63 m. Round your answer to one decimal place.Consider a see-saw with a total length of 11 m. A child with a mass of 31 kg sits on the very end of the see-saw. The child's parent, who has a mass of 89 kg, sits on the other side of the see-saw such that she balances the see-saw. How far from the pivot must the parent sit?You are looking for your iPhone and have decided to look under your couch. The couch is 2.6 m long and the centre of mass of the couch is 10.4 cm from the middle (towards one end). The couch has a mass of 92.4 kg. What is the minimum force required to lift one end of the couch in Newtons? Leave your answer to the nearest whole number.
Two big bugs, Buzz and Crunchy each of mass 0.65 kg, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 7.2 m and it rotates once every 1.2 s. What is the magnitude of the net force on Buzz, in Newtons? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
