Created by StemPy LabA small block is released from rest at the top of a smooth curved ramp, above a horizontal floor, as shown in the figure. At the bottom it slides onto the floor, where the coefficient of kinetic friction is . How far along the floor does it slide before it stops?

← A person of mass 60 kg stands on a weighing scale (marked in kg) in a lift. The lift starts from rest and goes down: first it speeds up at 2 m/s², then it moves at a steady speed, and finally it slows down at 2 m/s² before stopping. Taking g = 10 m/s², the scale reads, in these three stages,A small bead can slide without friction on a circular wire ring of radius 20 cm. The ring stands in a vertical plane and spins about its vertical diameter at 10 rad/s, as shown in the figure. Taking g = 10 m/s², at what angle from the lowest point of the ring (measured at the centre) can the bead stay at rest relative to the ring, apart from the bottom itself? →
