A 3.00-kg object is acted upon by an applied force causing it to move along a rough horizontal plane, with its x and y coordinates given by x = 5t² - 1 and y = 3t³ + 2, where x and y are in meters and is in seconds. The coefficients of friction between the object and the surface are 0.4 and 0.8. Answer the following questions: a. What are the units of the numerical coefficients? b. Determine the acceleration of the object as a function of time. c. Determine the Net force acting on the object at t = 5s.
