Question

Find the force acting on the body at an angle (lamda)
with the inclined plane when the body is on the point
of moving up along the inclined plane​

Answer 1

Answer:

Frictional force. The pull force is acting upon thebody because the body is moving on the inclined plane. The gravitational force is acting upon the bodybecause the body has certain amount of mass. The frictional force is acting upon the body because the surface of the inclined plane is rough.subtract Fi and Ff to work out the resultant force: F = 12.607 N - 3.005 N = 9.602 N. thus acceleration can be derived: a = 9.602 N / 2 kg = 4.801 m/s² the length ofinclined plane equals: L = 5 m / sin40° = 7.779 m. so the sliding time can be obtained: t = √(2 * 7.779 m / 4.801 m/s²) = 1.8 s.
