Explanation:
It is given that, in the first trial, the initial velocity is and in the second it is .
The total energy of the system remains constant. So,
....(1)
x is amplitude
It means that the amplitude is directly proportional to velocity. If velcoity increases to four times, then the amplitude also becomes 4 times.
Differentiating equation (1) we get :
Since,
and
So,
It means that the acceleration is also proportional to the amplitude. So, acceleration also becomes 4 times.
Hence, the correct option is (B) "both the amplitude and the maximum acceleration are four times as great"
You can spot the correct choice just by looking at their units.
Frequency has units of "per second".
a). and b). are distances, so that can't be it.
d). is time, so that can't be it.
c). is a number per second.
If there's a correct6 answer anywhere on this list,
then it has to be c).
