Robert is accelerating a cart at the rate of 2.2 meters/second2. if the mass in the cart is doubled, and the net force is also doubled, what is the final acceleration? a. the acceleration is halved. b. the acceleration remains the same. c. the acceleration is doubled. d. the acceleration becomes zero. e. the acceleration is quadrupled.

Answer;

B.  The acceleration remains the same.

Explanation;

F = ma  

the question said, F and M both are doubled ,so,  

2F =2ma

but you can see the result is same !!

so acceleration doesn't change,

Therefore; final acceleration is also 2.2

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
