    A child's toy of mass 5kg is pulled along level ground by a string inclined at 30 degrees to the horizontal. Denoting the tension in the string by T N, find in terms of T, an expression for the normal contact force between the toy and the floor, and deduce that T cannot exceed 98.

    Well, what are the forces acting on the toy? And what is the net vertical force on the toy?

    I found out the answer, its 49-1/2T thanks for being willing to help

    Normal contact force plus vertical force = 49 (which is the mass of the toy times by force of gravity,9.8). Vertical force is Tsin30...So, R plus Tsin30=49. R plus 1/2T=49. R=49-1/2T
