A 10 kg box is on a slippery ramp as shown in Figure 2.12. The coefficient of friction between the box and the ramp is just ?? = ??. ??.

a) What force is required to keep the box traveling up the ramp at a steady speed?

b) What has greater magnitude, the force applied by you or the gravitational force?

c) If you do not touch the box what will it's acceleration be?

If the angle of the ramp is raised to ??????then:

d) What force is required to keep it traveling up the ramp at a steady speed now?

e) What has greater magnitude, the force applied by you or the gravitational force?

f) If you do not touch the box what will it's acceleration be?

If the angle of the ramp is flattened to only ????then:

g) What force is required to keep it traveling up the ramp at a steady speed now?

h) What has greater magnitude, the force applied by you or the gravitational force?

i) If you do not touch the box what will it's acceleration be?
