In the figure, two blocks are connected by a string across a pully. m1 sits at rest on a table.
m1 = 3.4 kg. Use work and energy to find the speed of the m2 = 2.5 kg block just before it hits the floor in each of the following cases.
* Distance between the floor and m2 = 1.5
(a) The table is frictionless.
(b) The coefficient of kinetic friction of the 3.4 kg block is 0.15.
Please see the attached file for detailed solution.
(a) The tension of the cable is the internal force, ...
The solution is comprised of step-by-step calculation of the speed of the block m2 just before it hits the floor using work-energy theorem.
