A flatbed truck is carrying a heavy crate. The coefficient of static friction and the bed of the truck is 0.75. What is the maximum rate at which the driver can decelerate without having the crate slide against the cab of the truck?
a= ug, where a is acceleration u is the coefficent of friction and g is gravity.
I use 9.8 m/s as gravity, so your answer is -7.35/ms^2
