Unformatted text preview: b) Show that F r is perpendicular to j y i x r ˆ ˆ + = r . c) Find the work done by this force on a particle that moves once around a circle of radius 5 m centered at the origin. d) Explain if the force is conservative or not. 10.0 kg 5.0kg 2 4. A block slides on the frictionless looptheloop track shown below. Find the minimum height H at which it can be released from rest and still make it around the loop. 5. A small block of mass ‘m’ is placed inside an inverted cone that is rotating about a vertical axis such that the time for one revolution of the cone is ‘T’. The walls of the cone make an angle β with the vertical. The coefficient of static friction between the block and the cone is μ s . If the block is to remain at a constant height ‘h’ above the apex of the cone, what the minimum and maximum values of T? β h...
