The force of frictions is opposed to relative motion.
The acceleration of the crate is approximately <u>2.937 m/s²</u>.
Reason:
The given parameters are; 
The mass of the wood, m = 100 kg
The force which can move the wood, F = 588 N
Wood on wood static friction,  = 0.5
 = 0.5
Wood on wood kinetic friction,  = 0.3
 = 0.3
Solution;
The force of friction,  , acting when the crate is moving is given as
, acting when the crate is moving is given as 
follows;
 = m × g ×
 = m × g × 
Where;
g = The acceleration due to gravity ≈ 9.81 m/s²
Therefore, we have;
 = 100 × 9.81 × 0.3 = 294.3
 = 100 × 9.81 × 0.3 = 294.3 
The force of friction,  = 294.3 N
 = 294.3 N
The force with which the crate moves, F = 588 - 294.3 = 293.7
The force with which the crate moves, F = 293.7 N
Force = Mass, m × Acceleration, a

Therefore;

The acceleration of the crate, a ≈ <u>2.937 m/s²</u>.
