obtain the formula for the motion of the body down the plane of the hauling force (P) is parallel to the plane hence solve the problem below. a body of mass 20kg is placed on an incline of 30° to the horizontal is An object of mass 15kg is at the point of sliding down a plane inclined at 36° to the horizontal is μ=0.6. What force parallel to the plane will just move it down the plane (g=10m/s) ​
