Determine the speed of the block at b
WebApr 2, 2024 · The only change in its mechanical energy is the one due to the change of speed. This reduction of its kinetic energy, due to the conservation of energy, is equal to the work that friction does. We have that at A the kinetic energy is : K=1/2*m*u^2=10*10*10/2=500J. At B, we have that K=1/2*10*16=80J. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
