A boat and a trailer weighing a total of 450 lb are parked on a boat ramp with a 20° angle of inclination. Assume that the weight of the boat and the trailer is evenly distributed between two wheels. Part 1 of 3 (a) Write the force vector F in terms of i and j representing the weight of the boat and trailer for a single tire. Part 2 of 3 (b) Find the component vector of F parallel to the ramp in terms of i and j. Round intermediate and final values to one decimal place. (c) Find the magnitude of the force needed to keep the trailer from moving down the ramp. Round to the nearest pound.
