A student releases a marble from the top of a ramp and the marble increases speed steadily and travels 190 cm in 4.10 s what's the marbles final speed

The value is  

Explanation:

From the question we are told that

     The distance traveled is

     The  time taken is  

Generally from kinematic equation we have that

Here u is the initial velocity of the marble and the value is

So

=>  

=>    

Generally from kinematic equations we have that

=>  

=>  

Converting to  cm/s

=>    

=>    

answer; i believe that the correct answer is (d) a very small amount of mass
