A rollercoaster cart with a mass of 11 kg is travelling around a
vertical loop (circle) with a radius of 8 meters. At the top, it's
traveling at the minimum speed needed so that it remains in contact
with the track. If at some short time later it is at the side of
the loop (halfway between the top and bottom), what is the normal
force on the cart, in Newtons, if it loses 147 Joules of work to
non-conservative...

A 0.442 kg particle slides around a horizontal track. The track has a smooth, vertical outer wall forming a circle with a radius of 1.27 m. The particle is given an initial speed of 8.15 m/s. After one revolution, its speed has dropped to 6.11 m/s because of friction with the rough floor of the track. Calculate the energy loss due to friction in one revolution.Calculate the coefficient of kinetic friction.What is the total number of revolutions the particle makes...
