Question

a 15.0 kg mass and a 2.00 kg mass are connected bya string that passes over a frictionless pulley, the 15.0 kg mass lies on a smooth inclined at 45.0 solve for the acceleration of the masses and the tension in the string

Answer 1

m1•a=m1•g•sinα –T
m2•a=T-m2•g
a =g(m1•sinα-m2)/(m1+m2)
T= m2•a+m2•g= m2(a+g)
