Answer:
Step-by-step explanation:
In this case "solving" involves isolating the variable, x, on the left side of this equation.
Starting with x - 1/3 = 1/3, we add 1/3 to both sides. This results in:
x = 1/3 + 1/3, or x = 2/3.
The fraction for 3.20 is 16/5
Newton’s second law for the system of two boxes in the x-direction is given by:
F - f
k = (m + M )a
F - µk (m + M )g = (m + M )a
⇒ a = (F/m + M) - µkg = (150N / (4kg+10kg)) - 0.6(9.8m/s² ) = 4.83m/s²
For the top box, we get fs = ma = 4kg x 4.83m/s² =19.3N
