Two blocks are attached to opposite ends of a massless rope that goes over a massless, frictionless, stationary pulley. one of the blocks, with a mass of 5.0 kg accelerates downward at 34g.
what is the mass of the other block?

mass of other block is 0.7142 kg

Explanation:

given data

mass = 5.0 kg

accelerates downward =

to find out

mass of other block

solution

we will apply here Newton 2nd law that is

force ∑Fy = mass × acceleration

so

t - mg = ma    .............1

t = 5 ( 9.8 + )

t = 12.25 N

so other block mass is from equation 1

t - mg = ma  

t = m ( g+a)

12.25 = m ( g +   )

12.25 = m ( 9.8

m = 0.7142 kg

mass of other block is 0.7142 kg

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

conservation of mass

mass before something happens = mass afterwards
