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.© BrainMass Inc. brainmass.com September 24, 2018, 2:00 pm ad1c9bdddf - https://brainmass.com/physics/internal-energy/application-work-energy-theorem-188700
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.
