- Homework Statement
- Calculate the maximum acceleration of a car that is heading up a 4o slope (one that makes an angle of 4o with the horizontal) under the following road conditions. Assume that only half the weight of the car is supported by the two drive wheels and that the coefficient of static friction is involved—that is, the tires are not allowed to slip during the acceleration. (Ignore rolling.) (a) On dry concrete. (b) On wet concrete. (c) On ice, assuming that μ s = 0.100 , the same
as for shoes on ice
- Relevant Equations
- a=(g.sinθ+μs.g.cosθ)/2
θ = 4
μs = 1
Fnet = Wpararell + fs
m.a = 1/2.m.g.sinθ + μs.1/2.m.g.cosθ (divide by m)
a = (g.sinθ+μs.g.cosθ)/2
a = ((9.8)sin4 + (1)(9.8)cos4)/2
a = 5.23 m/s^2
hello guys, I'm having trouble with this problem. Can anybody help me correct my attempt and explain it to me?? thanks
