CO L1 LA 3. [1pt] *4 A wheelbarrow with content has a centre of mass at G; a force F - 138 N is applied at B at an angle 0 - 320. The net torque produced by this force and the weight about the axle at A is zero. Determine the mass of the wheelbarrow with content if L, = 0.29 m, L, = 0.70 m, L, = 0.48 m, and L. = 1.19 m
