This is a science question. What is the acceleration of the dragster?

8.89m/s^2

Explanation:

The question is asking what rate the dragster is accellerating. In science, acceleration is a change in velocity (speed) and direction. So, the speed decreases 40 m/s. It does this in 4.5 seconds. That's 40m/4.5 seconds. So, when you simplify that, it's 8.999999...m/s.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
