Arod of length l and mass m has a nonuniform mass distribution. the linear mass density (mass per length) is λ=cx2, where x is measured from the center of the rod and c is a constant. a. what are the units of c? mastering physics says the answer is: kg/m^3 but i don't understand where they got this answer. b. find the expression for c. mastering physics says the answer is 12m/l^3 --> no clue where they got this answer! c. find the expression for the moment of inertia of the rod for rotation about an axis through the center.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
