Answer
given,
force = 94 lb
weight of crate = 220 lb
Assuming the static friction be equal = 0.47
                        kinetic friction = 0.36
Maximum force applied to move the object is when object is just start to move.
 F = μ N
 F = 0.47 x 220
 F = 103.4 lb
As the frictional force is more than applied then the object will not move.
so, the friction force will be equal to the force applied on the object that is equal to 94 lb.
hence, the direction of force will left.
 
        
             
        
        
        
Hi!
The energy of the block is 4 m/s
To calculate this, you need to use the equation for 
kinetic energy. The block is sliding (i.e. it's moving). If the object is sliding across a level surface, the only energy it has is kinetic energy, because 
there is no change in potential energy (which changes with height). So, the mechanical energy will be pure kinetic energy. The equation is the following, derived from the expression for kinetic energy:
