A block of mass m1=16.6 kilogram rests on a frictionless ramp, which makes an angle italic theta (unknown) with respect to the horizontal. It is attached to a string that wraps over a mass less pulley. A block of mass m2=4.78 kilogram hangs vertically from the other end of the string. The whole system is initially held at rest. It is then released.
If the acceleration of m2 were measured to be 1.38 m/s2 upward, find what would be the magnitude of the tension, T, in the string?
