i solved this problem:

A student moves a box of books down the hall
by pulling on a rope attached to the box. The
student pulls with a force of 184 N at an angle
of 22.2? above the horizontal. The box has a
mass of 30.4 kg, and µk between the box and
the floor is 0.27.
The acceleration of gravity is 9.81 m/s2 .
Find the acceleration of the box.
Answer in units of m/s2.

the answer was: a= 3.5727 m/ s^2

I dont know how to do part B of it:

Student moves the box up a ramp
(with the same coefficient of friction) inclined
at 11.6? with the horizontal.
b) If the box starts from rest at the bottom
of the ramp and is pulled at an angle of 22.2?
with respect to the incline and with the same
184 N force, what is the acceleration up the
ramp?
Answer in units of m/s2.
