A flatbed turck 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?

✔ 最佳答案
maximum friction = mg(0.75)since F = ma
maximum deceleration, a = F/m = mg(0.75)/m = 0.75g = 7.5ms-2
