Horizontal frictionless track#
A small block of mass m = 4.5 kg is fired with an initial speed \(v_0\) = 8 m/s along a horizontal section of frictionless track, as shown in the top portion of the figure. The block then moves along the frictionless semicircular vertical track of radius \(R\) = 0.5m.
Determine the force exerted by the track on the block at point A.
Please enter in a numeric value in N.
The bottom of the track consists of a horizontal section (L = 13 m) with friction. Determine the coefficient of kinetic friction between the block and the bottom portion of the track if the block just makes it to point B before coming to rest.
Please enter in a numeric value.
