Question:
A block of mass 20 kg is at rest on a flat surface. The coefficient of static friction of the block-plane is 0.4 , and the coefficient of kinetic friction is 0.3. The block is pushed by a force T, which makes an angle of 37 degrees with the horizontal. Define:
a. The magnitude of the force T so that the block begins to move
b. After moving, determine the magnitude of the force T so that the block moves with constant velocity.
c. The block is moving with an acceleration of 2.0 m/^2
