Ago-cart travels around a flat, horizontal,
circular track with a radius of 25 meters. the
mass of the go-cart with the rider is
200. kilograms. the magnitude of the maximum
centripetal force exerted by the track on the
go-cart is 1200. newtons.
which change would increase the maximum
speed at which the go-cart could travel without
sliding off this track?
(1) decrease the coefficient of friction between
the go-cart and the track.
(2) decrease the radius of the track.
(3) increase the radius of the track.
(4) increase the mass of the go-cart.
