Students make a small elevator machine with 5 kg and 10 kg masses on either side how fast will the masses accelerate once they are released?

The acceleration of the elevator machine is, a = 3 m/s²                

Explanation:

Given data,

The mass on the one end, m = 5 kg

The mass on the other end, M = 10 kg

According to the Atwood's machine

                    Ma = Mg - T

                     ma = T - mg

Adding those equations,

                   a (M + m) = g ( M - m)

                       a = (M + m) / ( M - m)

Substituting the values,

                       a = (10 + 5) / (10 - 5)

                          = 3 m/s²

The acceleration of the elevator machine is, a = 3 m/s²                

How to prevent cancer:

       Cancer avoidance is a step taken to reduce the risk of cancer. This could include keeping a safe diet, avoiding contact to suspected cancer-causing chemicals, and taking medications or vaccinations that may prevent cancer cells from growing.

       Be shure to be taking steps after seeing warning signals that include; changes in bowel or bladder habits; A sore that doesn't heal, Uncommon bleeding or discharge, Tightening or lumping in the breast or elsewhere, Indigestion or trouble chewing, An noticeable improvement in wart or mole, or in Nagging cough or hoarseness.
