I know this question is probably increadibly easy...its listed as an easy problem in the book...but it is not clicking.

I believe I have to use the thrust = (delta m/delta t) x v but I think I am setting it up wrong.

I had 2.8 as the thrust as this is the amount of force needed to keep an average speed so

2.8 = (0.59/x) x 10

which leads to 5.9/2.8

which equals 2.1 seconds in time....

If this first part is correct, then i am having trouble converting this time into amount of rocks.

I suspect I set the first part up wrong though
