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. 9. What is the minimum magnitude of P needed to start the object to displace horizontally? 10. What is the magnitude of the acceleration vector of the object when the value magnitude of P is equal to 8,000 N? Express your answer in unit of m/s^2 11. What is the magnitude of the velocity vector of the object after 5 seconds when the magnitude of P is equal to 8,000 N? Express your answer in unit of m/s 12. What is the total distance travelled by the object after 5 seconds when the magnitude of P is equal to 8,000 N? Express your answer in unit of m 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.
