An object weighing 500kg is to be pulled by a man by exerting a force P. Force P is inclined at an angle of 25 deg. measured from the positive axis. The object and the floor has a coefficient of friction: static = 0.35 and dynamic = 0.15. 13. What should be the magnitude of P to cause an acceleration to the object equal to 0.51 m/s^2. Express your answer in unit of kN. 14. From item 13, when the required value of P is applied, what would be the magnitude of the velocity of the object after 10s? Express your answer in unit of m/s 15. From item 13, when the required value of Pis applied, what would be the total distance travelled by the object after 10s? Express
