The velocity is the integral of acceleration. If acceleration is 100 m/s^2 then velocity is:

So to know the velocity at any time, t, we just put t in seconds into this equation. To know at what time we get to a certain velocity, we set this equation equal to that velocity and solve for t:
From the choices provided, the better answer is ' T ' .
I think it would be yes because the drum is submerged in water and the water would slow the sound waves, making the sound softer. Right?
