∆L=L¹ - L² = 15cm - 10cm = 5cm = 0.05m F= 150N X 0.05m = 7.5N W = FD =7.5N X 0.05m =0.375J
Since you know the Fg (which is 0.6kN * 1000 = 600N), you can use that to find the mass of the object: mg = Fg mg = 600 m(9.8) = 600 m = 61.2 Now, you use the sum of forces formula, keeping in mind that you have 2 forces in the vertical direction: Ft and
