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?

1) 3.9 m/s2
2) 8.8 m/s2
3) 24 m/s2
4) 180 m/s2
5) 400 m/s2

2) 8.8 m/s2
m•a=F(fr)=μ(s) •m•g
a= μ(s) • g
