Answer on Mechanics | Relativity Question for john
A cylinder has length (L). The cylinder is resting at the bottom of a surface with an incline (a) above the horizontal. The cylinder has mass (m) and radius (R), it is free to rotate about an axis through its center (of the cylinder). The coefficent of static friction between the cylinder and the surface is (u). Block (B), with mass (Mb), is suspended in the air with a distance (d) above the ground. Block (B) is connected to the axis that runs through the cylinder, by a light string, passing (parrallel to the firts surface) over a frictionless pulley with a mass of (Mp) and a radius (Rp). The string doesnt slip over the rim of the pulley.
_ Use newton's laws to determine the acceleration of the system as block B is falling.
_ Use the law of conservation of energy to determine the acceleration of the system as block (B) is falling.
