Question

A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 2.0 m/s at the end of 3.0 s. At that instant, the kinetic energy of the system is 50 J and each mass has moved a distance of 3.0 m. Determine the values of m1 and m2. Show step by step solution.

At that instant, the kinetic energy of the system is 50 J and each mass has moved a distance of 3.0 m. Determine the values of m1 and m2. Show step by step solution.

Explanation / Answer

energy is constant so (m1-m2)*10*3 =50 and 0.5*(m1+m2)*4 = 50 m1=40/3 Kg m2 = 25/3 Kg
