How far will a 68 kg box slide across a horizontal surface after it's placed on a 60-degree ramp, 8.3 m far up (on) the incline (not the height) if: a) The ramp is frictionless, but the ground after it has a coefficient of 0.193. Explain/Show your work. b) The ground is frictionless, but the ramp has a coefficient of 0.193. Explain/Show your work. c) The ramp and the ground both have a coefficient of 0.193.Explain/Show your work. d) Now both ramp and ground are frictionless - what is the final velocity of the box at the bottom of the ramp? Explain/Show your work.
