Two blocks are connected by a massless rope that passes over a 1 kg pulley with a radius of 12 cm. The rope moves over the pulley without slipping. The mass of block A is 2.1 kg and the mass of block B is 4.1 kg. Block A is also connected to a horizontally-mounted spring with a spring constant of 358 J/m2. What is the angular frequency (in rad/s) of oscillations of this system

Explanation:

From the question we are told that:

Mass of pulley

Radius

Mass of block A

Mass of block B

Spring constant

Generally the equation for Torque is mathematically given by

Since

At mass A

At mass B

At  Pulley

Therefore the equation for total force F

At mass A+At mass B+At  Pulley

Since From above equation

Therefore

Generally the equation for frequency is mathematically given by

the answer is d. 4

hope this

also the more points you give the faster your questions get answered

it is called kinetic energy
