Homework Statement
Water is poured into a container that has a leak. The mass m of the water is given as a function of time t by m = 6.00t 0.8 - 2.75t + 22.00, with t
(a) At what time is the water mass greatest? (s)
(b) What is that greatest mass? (g)
(c) In kilograms per minute, what is the rate of mass change at t = 2.00 s? (kg/min)
(d) In kilograms per minute, what is the rate of mass change at t = 5.00 s? (kg/min)
Homework Equations
m = 6.00t 0.8 - 2.75t + 22.00
The Attempt at a Solution
I didn't really have any clue on how to start this problem at all, so I was just able to find that the greatest mass is ~33.1 grams from guessing and checking. After that, I tried to see if I could work out what the time was by plugging the mass back into the equation, but the answer I got (17.7 seconds) was showing as incorrect on Webassign. So I really just need to be explained how to even start this problem in the first place so that I can work from there.
