a) A force F=(x÷a-1) is acting on a particle along the x-axis. Determine the work done by the force in moving the particle from x=0 to x=2a.
b) A block of mass 6.0 kg slides from rest at a height of 2.0 m down to a horizontal surface where it passes over a 1.5 m rough patch. After crossing this patch it climbs up another incline which is at an angle of 30° to the ground. The rough patch has a coefficient of kinetic friction . µk=0.25 What height does the block reach on the incline before it comes to rest?
