Answer: hello your question is poorly written attached below is the complete question
answer :
TA = 1.6*10^-24 * 60 * 2,  TB = 1.6*10^-24 * ( 60 + 30 ) * 2  -- ( option 1 )
Explanation:
a = 2m/s^2 
Ta = m₁ a = 60 * 1.6 * 10^-24 * 2 ц
Tb - Ta = m₂ a 
∴ Tb = m₂ a  + Ta 
        = ( 30 * 1.6 * 10^-24 * 2 ) +  ( 60 * 1.6 * 10^-24 * 2 )
= ( 30 + 60 ) * 1.6 * 10^-24 * 2 ц
 
        
             
        
        
        
Answer:
inertia
Explanation:
The property of matter that will keep the body in motion when the car comes to a halt is the inertia force. 
Inertia is the ability of a body to remain in static position. It is the tendency to remain in a stable condition where there is no motion. 
- Newton's first law is the law of inertia and it states that a body remain in a state of rest or of uniform motion unless acted upon by an external force. 
- The ability to remain in state of rest by a body is predicated on the force of inertia. 
 
        
                    
             
        
        
        
Use the definition of acceleration:
Acceleration = (change of velocity) divided by (time for the change)
The graph says:
Change of velocity = -6 m/s
Time for the change = 3 sec
So Acceleration = (-6m/s) / (3 s)
That's -6/3 m/s•s
or
-2 m/s^2
