The following situation is identical for questions 6, 7, and 8: A mass on a frictionless ramp is given a push so that it starts to slide up the ramp. After the initial push, the force of the initial push no longer acts, and the mass freely slides up the ramp, eventually reverses direction and slides back down. Select the option which best describes the net force on the mass as the mass is moving up the ramp after being released. Net constant force down the ramp O Net increasing force down the ramp O Net decreasing force down the ramp O Net force of zero Net constant force up the ramp O Net increasing force up the ramp O Net decreasing force up the ramp
