At a construction site, a large rock is being moved by two tractors pulling on the rock as shown. This picture is looking down from above and the ground is flat and horizontal. You can consider the x-direction to be East and the y-direction to be North. The rock is being dragged, and accelerate, in the direction of the red arrow. The tension in Rope 2 is FT2 = 484 Newtons and the angle is 0 = 29 degrees. The coefficient of kinetic friction along the ground is k = 0.18 If the acceleration of the rock is a = 1.77 m/s, what is the mass of the rock? Give your answer in kg to at least three significant digits to avoid being counted off due to rounding. Do not include the units with your answer. Rope 2 a Rope 1 y x
