Answer:
 Kinetic energy is 242.7 Joule
Explanation:
m = 47.4 kg
v = 3.2m/s²
Now,
K.E. = 1/2 × m × v²
or, K.E. = 1/2 × 47.4 × 3.2²
or, K.E. = 242.7 Joule
 
        
             
        
        
        
I'm pretty sure the answer is <u>A - It combines the gas-powered engine and an electric motor into one system.</u>
        
             
        
        
        
A change in an object's speed has a(n) _________ effect on its kinetic energy than a change in its mass = <span>A greater effect.</span>
        
                    
             
        
        
        
Answer:
 the second law states that the force F is the product of an object's mass and its acceleration a: F = m * a. For an external applied force, the change in velocity depends on the mass of the object.
