hi there! i can't quite recall the formula for vertical velocity and who to easily factor the polynomials. Help anyone?
here's my example problem:
A cricket jumps off the ground with an initial vertical velocity of 4 ft per second.
A. write an equation that gives the height (in feet) of the cricket as a function of the time (in seconds) since it jumps.
B. after how many seconds does the cricket land on the ground?

thank you! i don't want you to necessarily solve this for me, i just need a little bit of a prompt with how to solve this! thanks so much!

So you can use $y=y_0+v_{0y}t-16t^2$, where $y_0$ is the initial height, and $v_{0y}$ is the initial velocity in the $y$ direction. Can you proceed from here?
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
