Masses M(1), M(2) and M(3) are connected...

Masses `M_(1), M_(2)` and `M_(3)` are connected by strings of negligible mass which pass over massless and frictionless pulleys `P_(1)` and `P_(2)` as shown in the figure. The masses move such that the portion of the string between`P_(1)` and `P_(2)` is parallel to the inclined plane and the portion of the string between `P_(2)` and `M_(3)` is horizontal. The masses `M_(2)` and `M_(3)` are 4.0 kg each and the coefficient of kinetic friction between both the masses and the surfaces is 0.25. The inclined plane makes an angle of 37° with the horizontal. If the mass `M_(1)` moves downwards with a uniform velocity, find
(i) the mass of `M_(1)` in kg
(ii) the tension in the horizontal portion of the string in Newton

Masses M_(1),M_(2) and M_(3) are connected by string of negligible mass which pass over massless and frictionless pulleys P_(1) and P_(2) as shown in figure 7.15. The masses move such that the string between P_(1) and P_(2) is parallel to the incline and the portion of the string between P_(2) and M_(3) is horizontal. The masses M_(2) and M_(3) are 4.0 kg each and the coefficient of kinetic friction between the masses and the surfces is 0.25. The inclined plane makes an angle of 37^(@) with the horizontal. If the mass M_(1) moves downwards with a uniform velocity, find (i) the mass of M_(1) , (ii) the tension in the horizontal portion. (g=9.8 ms^(-2) , sin 37^(@)=(3)/(5))
