SUMMARY

The problem involves calculating the total volume of water pumped from a lake using the rate function R(t) = 12√(t / (t + 1)) cubic meters per minute over the interval from t = 0 to t = 5 minutes. The integration of this function from 0 to 5 will yield the total volume in cubic meters without the need for unit conversion, as the problem does not specify a particular unit requirement. Therefore, the solution focuses solely on evaluating the definite integral of the given rate function.

PREREQUISITES
  • Understanding of definite integrals in calculus
  • Familiarity with the concept of rate functions
  • Knowledge of cubic meter as a volume measurement
  • Basic algebraic manipulation skills
NEXT STEPS
  • Practice evaluating definite integrals with variable limits
  • Explore applications of rate functions in real-world scenarios
  • Learn about unit conversions in volume calculations
  • Study the properties of square root functions in calculus
USEFUL FOR

Students studying calculus, particularly those focusing on integration techniques, as well as educators and tutors looking to enhance their understanding of applied rate problems in real-world contexts.

Homework Statement



Water is pumped out of a lake at the rate R(t) = 12*SQUAREROOT(t / t+1) cubic meters per minute, where t is measured in minutes. How much water is pumped from time t = 0 to t = 5 ?

The Attempt at a Solution


I cannot figure out if the integration of times 0 and 5 are all that is required or if I will have to also convert cubic meters before completing problem.
 
Physics news on Phys.org
the integration would leave you with cubic meters anyway, you wouldn't need to do any converting
the question also doesn't ask for a specific unit so I'd guess you would be alright using whatever units you wanted
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
