2.(Ramp section) Suppose the height of the ramp is h1= 0.40m, and the foot of the ramp is horizontal, and is h2= 1.5m above the floor. What will be the horizontal distance traveled by the following four objects before they hit the floor? Assume that R= 15mm in each case; assume that the density of steel is 7.8 g/cm3; and assume that the density of aluminum is 2.7 g/cm3.a. A solid steel sphere slidingdown the ramp without friction. b.A solid steel sphere rollingdown the ramp without slipping. c.A spherical steel shell with shell thickness 1.0 mm rollingdown the ramp without slipping. d.A solid aluminum sphere rollingdown the ramp without slipping.

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
