Answer:
The dimension of the nullspace of T = 4
Explanation:
The rank/dimension theorem is explains that:
Suppose V and W are vector spaces over F, and T:V → W is linear. If V is finite dimensional, then
nullity(T) + rank(T) = dim(V).
rank(T) = dimension of T = dim(T) = dim(W) = 7
nullity(T) = dimension of the nullspace of T = dim(T) = ?
dim(V) = 11
nullity(T) = dim(V) - dim(T) = 11 - 7
nullity(T) = 4.

the more mass something has the more force it takes to move said object.
 
        
                    
             
        
        
        
Given parameters: 
Initial velocity  = 0m/s 
Acceleration  = 2.857m/s²
Time  = 15.5s 
Unknown: 
Final speed of the car = ? 
Solution: 
  We use one of the motion equations to solve this problem; 
      V = U + at 
   Where V is the final velocity 
                U is the initial velocity
                a is the acceleration 
                 t is the time taken
     V = 0 + 2.857 x 15.5  = 44.28m/s
