A flatbed egg truck is in a drag race. The truck is carrying a 450 lb. crate of eggs in the back. The coefficients of friction between the crate and the truck bed are μs = 0.9 and μk = 0.4. What is the maximum acceleration the truck can have without the eggs sliding off the back of the truck?

Answer 1

m•a=F(fr)=μ(s)•m•g
a= μ(s)•g
