Question

A sphere of mass mi and a block of mass m2 are connected by a light cord that passes over a pulley, as shown in the figure. T

Answer 1

Answer #1

At any instant of time the sphere and the block have a common speed v, so the angular moment of the sphere about the pulley axle is miVR

and block is mVR

and the angular momentum of the pulley is

Now,

the total external torque about the pulley axle is

ET ont dit m. gr - d[ 3 L = mvR+ M₂ V R + MVR - mive & My VR + Iw MIUR + m₂ VR + I (VIR) = v(me me R +/) mige & d [ MR & M2 R

Hence,

the expression of linear acceleration is

a = migR miR+ m2R+
