A student pulls a box of books on a smooth horizontal floor with a force of 100 N in a direction of 37 degrees

0 kg, what is the acceleration of the box?since the floor is frictionless, there is no opposing friction force,a = 2.0m/s/s-100cos37 gives you the force in the horizontal direction and 100cos37 / 40 = 1.......

above the horizontal. If the mass of the box and the books is 40.0 kg, what is the acceleration of the box?

-

the acceleration will be caused by the horizontal component of the pulling force

since the floor is frictionless, there is no opposing friction force, so we have

horizontal component of pulling force = ma

100 cos 37 = 40 a

a = 2.0m/s/s

-

100cos37 gives you the force in the horizontal direction and 100cos37 / 40 = 1.99658 m/s^2
