Answer: Last option 
2.27 m/s2
Explanation:
As the runner is running at a constant speed then the only acceleration present in the movement is the centripetal acceleration.
If we call a_c to the centripetal acceleration then, by definition

in this case we know the speed of the runner

The radius "r" will be the distance from the runner to the center of the track



The answer is the last option
 
        
             
        
        
        
Answer:
 
Explanation:
Assuming the we have to find ratio maximum forces on the mass in each case 
we know that in a spring mass system 
F= Kx 
K= spring constant 
x= spring displacement 
Case 1:

case 2:

therefore, 
 
 
        
             
        
        
        
Because thats the motor working hard to process food
