Answer:
The correct answer will be " ". The further explanation is given below.
". The further explanation is given below.
Explanation:
The potential energy will be, 
⇒  
The expression of force will be, 
⇒  
⇒      
⇒      
Force seems to be appealing because the expression has been negative. It therefore means that the force or substance is acting laterally in on itself.
 
        
             
        
        
        
Answer
It will stay the same!
Explanation:
If you so happen to move something from left to right, the size of it is not being shrunk or expanded in any type of way, shape, or form.
 
        
             
        
        
        
Answer: 2812500 joules
Explanation:
Mass of car = 1500kg
Velocity of car = 75mph
Kinetic energy = ?
Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass M and velocity, V
Thus, Kinetic energy = 1/2 x mv^2
 = 1/2 x 1000kg x (75mph)^2
= 0.5 x 1000kg x (75mph)^2
 = 500 x 5625
 = 2812500 joules
Thus, the car travels with a kinetic energy of 2812500 joules
 
        
             
        
        
        
Answer:
-30m/s
Explanation:
Given:
Initial velocity of object  = 200 feet/second
Final velocity of object  = 50 feet/second
Time of travel = 5 seconds
To calculate acceleration of the object we will find the rate of change of velocity with respect to time.
So, acceleration "a" is given by:

where vf represents final velocity, vi represents initial velocity and  is time of travel.
Plugging in values to evaluate acceleration.



The acceleration of the object is -30m/s
