suppose the height of the ramp is h1=0.3 m, and the foot of the ramp is horizontal, and is h2=1.00 m above the floor. what will be the horizontal distancec traveled by the following four objects before they hit the floor? Assume that R=12.7 mm in each case; assume that the density of steel is 7.8 g/cm^3; and assume that the density of aluminum is 2.7 g/cm^3.

a) A solid steel sphere sliding down the ramp without friction.

b)a solid steel sphere rolling down the ramp without slipping.

c) A spherical steel shell with shell thickness 10 mm rolling down the ramp without slipping.

d) A solid aluminum sphere rolling down the ramp without slipping.
