SUMMARY

The discussion focuses on solving the equation √(x + (4/3)y) / p, where p is given as 3.4 e3 Kg m⁻³, x as 1.6 e11 N m⁻², and y as 6.4 e10 N m⁻². Participants emphasize the importance of using base units (kg, m, s) throughout the calculations to ensure accuracy. The final result should be converted from meters per second (m/s) to kilometers per second (km/s) for clarity. This approach simplifies the problem and aids in achieving the correct answer.

PREREQUISITES
  • Understanding of basic algebra and equations
  • Familiarity with unit conversions, specifically from m/s to km/s
  • Knowledge of physical quantities such as pressure (N m⁻²) and density (Kg m⁻³)
  • Ability to manipulate square roots and fractions in mathematical expressions
NEXT STEPS
  • Learn about dimensional analysis for unit conversions
  • Study the properties of square roots in algebra
  • Explore the relationship between pressure, density, and other physical quantities
  • Practice solving equations involving multiple variables and units
USEFUL FOR

Students in physics or engineering, mathematicians, and anyone involved in solving equations related to physical quantities and unit conversions.

Heres the question – :bugeye:

√ x + 4/3 y
√ p
(this whole equation should be squared, but not sure how to make the square root symbol big enough)

p = 3.4 e3 Kg m-³

x = 1.6 e11 N m-²

y = 6.4 e10 N m-²

I need to calculate the answer and give my answer in Km s-1 (Km per second)

Any ideas?? :confused:

I don't understand... are you just trying to substitute them in?
 
If the problem is with the units, just use base units all the way through (kg, m, s) and then your final answer will be in m/s. Then its easy to convert m/s to km/s.
 
thank you for the advice, I will have another go
