A flatbed truck is carrying a heavy crate. The coefficient of static friction between the crate and the bed of the truck is (0.75). What is the maximum rate at which the driver can decelerate and still avoid having the crate slide against the cab of the truck?

The maximum frictional force will be   csf  m g

  If the force is greater or equal to this, the mass will slide

 

csf m g  =  ma     This 'a' is the decelleration max magnitude when the mass , m , will slide

 

csf g = a

.75 (9.81) = 7.358 m/s^2  DEceleration
