In this experiment, (S) is compressed to a spring (R) by a distance x-5cm, and then released for to-0. (S) rolls along the frictionless horizontal plane FG with a speed v, and then rolls up the inclined GH. We also consider gra wh the horizontal plane passing through FG as the reference of gravitational potential energy. Given: the spring constant of (R) =k=720 N/m. and a=30°. A. Find the numerical value of v. B. Find the mechanical energy of the system when (S) is at point G. C. (S) reaches appoint K, on the line of greatest slope GH, and turns back. Knowing that GK=50cm, calculate the mechanical energy K a-30 of the system when (S) is at K. D. Is the mechanical energy of the system conserved? Justify. E. Deduce the magnitude f of the force of friction, assumed to be constant along the inclined. F G
