Your friend gets a flat tire while driving up a road with a 35.0degree slope. while changing the tire he lets go of the spare and it begins to roll down the hill. his sister has stopped her car 4.51 m down the slope (of course this is very late on a cloudy night so she is there with her lights on). if we model the tire as a cylindrical shell with mass m and radius r that rolls without slipping. how fast (m/s) is the tire moving when it hits the sister's car? if instead we model the tire as a solid cylinder, how fast (m/s) would it be moving when it hits the sister's car?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
