How do I find the Laplace Transform for U3(t)(t-3)^5/2?

Click For Summary
SUMMARY

The discussion focuses on finding the Laplace Transform for the function ${U}_{3}(t)(t-3)^{5/2}$. The user references the formula for Laplace transforms involving the unit step function, specifically ${f(t)=g(t)u(t-a)}$, where the transform is given by $F(s)=e^{-as}\mathcal{L}\{g(t+a)\}(s)$. The user initially struggles with the problem but ultimately resolves it independently.

PREREQUISITES
  • Understanding of Laplace Transforms
  • Familiarity with the unit step function, U(t)
  • Knowledge of the properties of the Laplace Transform
  • Ability to manipulate functions involving shifts and scaling
NEXT STEPS
  • Study the properties of the Laplace Transform, focusing on the shifting theorem
  • Practice finding Laplace Transforms of piecewise functions
  • Explore advanced applications of the Laplace Transform in differential equations
  • Learn about the inverse Laplace Transform and its applications
USEFUL FOR

Students and professionals in engineering, mathematics, and physics who are working with Laplace Transforms, particularly those dealing with piecewise functions and unit step functions.

I'm working on a few problems to find Laplace transforms and I got stuck on this one.
${U}_{3}(t){(t-3)}^{5/2}$

It looks different from the other I've been doing so I don't really know how to get started
 
Physics news on Phys.org
According to a table I have, if we are given:

$$f(t)=g(t)u(t-a)$$ where $0\le a$

then:

$$F(s)=e^{-as}\mathcal{L}\{g(t+a)\}(s)$$

Does this help?
 
thank you :) i didn't notice anything of that form in my table
 
So I tried to work on this problem but I can't seem to figure it out. I just have no idea what I'm doing with it.
 
nervmind! got it
