Answer:
Left
Explanation:
newtons is a measure of force. Since there is more newtons(force) pushing to the left, the object will move left. the 15 newtons cancel each other out, leaving only 5 newtons pushing to one side with no resistance.
 
        
                    
             
        
        
        
Answer:
A= 148.92  m/s²
Explanation:
Given that
 U(x,y) = (6.00  )x²  - (3.75  )y ³
m= 0.04 kg
Now force in the x-direction
Fx= - dU/dx
 U(x,y) = (6.00  )x²  - (3.75  )y ³
dU/dx= 12 x
When x=0.4 m
dU/dx= 12 x 0.4 = 4.8 
So we can say that
Fx= - 4.8 N
From Newtons law
F= m a
- 4.8 = 0.04 x a
a = -120 m/s²
Acceleration in x direction ,a = -120 m/s²
In y -direction
F= - dU/dy
 U(x,y) = (6.00  )x²  - (3.75  )y ³
dU/dy = 0 - 3.75 x 3 y²
When y = 0.56 m
dU/dy = - 3.75 x 3 x 0.56 x 0.56 
dU/dy = - 3.52 
So we can say that force in y -direction
F= 3.52 N
F= m a'
3.52 = 0.04 x a'
a'=88.2 m/s²
acceleration in y direction is 88.2 m/s²
The resultant acceleration 


A= 148.92  m/s²
 
        
             
        
        
        
Explanation:
Use Pythagorean theorem:
r² = x² + y²
r² = (-6.46 m)² + (-3.78 m)²
r = 7.48 m
 
        
             
        
        
        
Uranus is much much larger than Earth, so the distance from the planet's center is much much greater
