Question 313641
the horizontal component of the string tension equals the horizontal force of 12N


the vertical component of the string tension equals the force of gravity ___ mg = 3 * 9.8 = 29.4N


a)  by Pythagoras ___ T^2 = 12^2 + 29.4^2


b)  the tangent of the angle is the horizontal component divided by the vertical component
___ tan(Θ) = 12 / 29.4
