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
