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. Websqrt (5gr) is the speed required at the BASE of the loop de loop. So the kinetic energy at the base is 1/2 mv^2 = 5/2 mgr Using the conservation of mechanical energy, we get 5/2 mgr -2mgr = 1/2 mgr at the TOP of the loop. (this is kinetic energy) and again using Ek = 1/2 mv^2, The speed at the TOP is sqrt (2gr), as Sal has mentioned.
