Question

A block of mass m1 = 3.27 kg on a frictionless plane inclined at angle ? = 31.2

Answer 1

m1 = 3.27 Kg

m2 = 2.38 Kg

Angle of inclination ? = 31.2 degrees

(a)

Acceleration of hanging mass a = [(m1 sin? - m2)/(m1+ m2)]g

                                               = [0.993/9.23]9.8

                                               = -1.19 m/s^2

(b)

Tension in the string T = m1m2g(1 + sin?)/(m1 + m2)

                                    = 20.492 N
