A horizontal force F is applied to block X, resulting in it accelerating with 1,5 m. s? to the
right. The kinetic coefficient of friction along the rough surface BC, is 0,4. The inclined
plane surface AB, is frictionless. The angle between the inclined plane and horizontal is
20.
2.1 State Newton's Second Law in words.
(2)
2.2 Draw a labelled free-body diagram indicating all the forces acting on block Y,
while it is moving towards B on the inclined plane.
(3)
2.3 Calculate the magnitude of the tension T, in the string, connecting the block X
and block Y, while force F is applied.
(4)
(5)
2.4 Calculate the magnitude of the horizontal force F, applied to block X.
