A boy pulls with a force of 10 N a box with a string that makes an angle of 30 degrees. with the horizontal. the mass of the box is 5 kg. the box moves with constant velocity. Calculate:

a. the weight of the box is: ________

b. the vertical component that makes the string over the box is: _____________

c. the perpendicular force that the floor makes over the box is:_________

d. the horizontal component that the force makes over the box is:________________

e. the kinetic frictional force is:_____________
