Hi,

I believe the correct answer to this problem would be B becausethe mass would decrease allowing it to faster, but I want to doublecheck. Please let me know if you agree or if you do not, then howyou would obtain the correct answer.

12. A truck loaded with sand accelerated along a highway. Thedriving force on the truck remains constant. What happened to theacceleration of the truck as its trailer leaks sand at a constantrate through a hole in its bottom?

A. It decreases at a steady rate.

B. It increases at a steady rate.

C. It increases and then decreases.

D. It decreases and then increases.

E. It remains constant.

Thanks,

Explanation / Answer

F=ma Since the Force is a constant, the mass and the acceleration areinversly related. So if the mass decreases at a steady ratethe acceleration must increase at a steady rate. Your answer wascorrect.
