Due:

$2.$ A body having a mass of $200kg$ is supported on an inclined plane that forms an angle of ${40}^{**}$ with the horizontal as shown. A force $P$ parallel to and acting up the plane is applied to the body. The coefficient of static friction is $0\mathrm{.}6.($a$)$ Find the value of $P$ to cause motion to impend up the plane. $($b$)$ Find the value of $P$ to cause motion to impend down the plane. $($c$)$ If $P=500N,$ determine the magnitude and direction of the resisting friction force. $($Do not forget to change the values on the pictures to what is provided in the text of the problem$).$
