Question

Describe the motion of block A moml the time ti when Sinkes the oor to the time t2 When block A Ae) bescribe the table. leaves the (f Determine the speed with which block A strikes the floor. Problem 2 (12 points) A horizontal force F is applied to a small block of mass mi to make F No Frietioo it slide along the top of a larger block of mass m2 and length The coefficient ofkinetic friction between the blocks is H. The larger block slides without friction along a horizontal surface. The blocks start from rest with the small block at one end of the larger block, as shown. (a) Draw a free body diagram of each of the blocks. (b) In terms of the given and any necessary physical constants, find the acceleration of each block, ai and a2, relative to the horizontal surface. (c) In terms of l ,al, and ar, find the time t needed for the small block to slide off the right-hand end of the larger (d) block. show your process, or explain your reasoning. between the two blocks. Find an expression for the energy dissipated as heat because of the friction

Explanation / Answer

Here

heat energy is only due to friction between the blocks so that energy will be equal to the work done by athe friction about the distance l

that is

   the frictional force f = mue*m1*g cos theta

and work done is f*s = mue*m1*g cos0 *l

due to friction the energy will be dissipated in the form of heat energy .

   = mue*m1*g*l
