A block of mass m = 5.0 kg hangs from a very light rope wrapped around a cylinder with radius R = 10 cm. A force F = 70.0 N pulls from the free end of the rope (see picture) and causes the block to go up with an acceleration of 2.0 m/s². The moment of inertia of the cylinder is I = 1/2 MR². Find: Please include free body diagrams, force and torque equations. 1. The tension on the side of the rope that is connected to the block. 2. The mass M of the cylinder.

00:01 Hello student, to solve the given question, let us write the formula for torque that is equal to force into perpendicular distance.
00:08 Now using this relation, we can solve the question.
00:11 Firstly, let us write the equation of motion for mass, which will be tension force t1 minus mg equals ma.
00:23 Mark it as equation number one for further use.
00:26 Now let us write the torque equation.
00:27 It will be force multiply by distance r minus tension force multiply by distance r equals net torque that is i alpha here let us take the common factor r from here f minus t1 will be equal to here plug in the value for i and alpha 1 by 2 mr square multiply by a by r so after canceling r from both sides the equation will become f minus t1 equals half m a market as equation number two now adding equation one and two we get f minus m g equals m plus m by two multiply by a from here we can calculate the mass plug in the values 70 minus 5 into 9 .8 equals 5 plus m by 2 multiply by a...
