Homework Answers
Answers:
1) as the crate is not slipping , it is also accelerating to left
hence , the direction of friction force on the crate is
To the left
---------------------------------------
2) what is the direction of the friction force on the truck , due to block
according to Netwon's third law
the direction of friction will be opposite on truck
the direction of friction on truck is
the the right
---------------------------------
3) what is the direction of the friction force on the truck , due to road
it is in the direction of acceleration
the direction of force is
To the left
---------------------------
4)
as the direction of acceleration is to the left
the direction of total friction is
To the left

m A box rests on top of a flat bed truck. The box has a mass of m = 16 kg. The coefficient of static friction between the box and truck is is = 0.82 and the coefficient of kinetic friction between the box and truck is Hk = 0.64. 1) The truck accelerates from rest to Vp = 19 m/s in t = 13 s (which is slow enough that the box will not slide). What is the acceleration...
