**Damon**, Saturday, February 5, 2011 at 5:18pmforce parallel to slope = .3 g m + m g sin 10 down slope = .474 m g

force normal to slope = m g cos 10 =.985 m g

tan angle relative to normal to slope = .474/.985 = .481

so

angle relative to normal to slope (straight down in the car) = 25.7 degrees or 15.7 degrees from direction to earth center
