of ‘B’,
A Bo X B (1) ñ Ө w, a Platform S 0 Fixed platform cord arc length angle Plus rotation (Question 1) A disk, 'A' in the figure is moving along a straight-line path (upward) in the air, whereas a disk, 'B' is rotating with the initial velocity in the tangential direction, 10.0 (m/s) at the initial point, (1) (S = 0) along a circular path having a radius of curvature, PB = 400 (m) on the fixed platform (it does not rotate). The friction coefficient is µ = 0.1 between the platform and 'B'. The cord breaks when the tension of it reaches up to 3 (N). The mass of each disk is 3 (Kg). The acceleration of 'A' is a = 5 (m/s²) in Y-direction. Gravity, g = 10 (m/s²).
