Write an equation that expresses the following relationship. u varies jointly with p and d and inversely with w in your equation, use k as the constant of proportionality.

Let's explain what direct and indirect variation mean:

for some nonzero constant that is the constant of variation or the constant of proportionality.

for some nonzero constant , where is also the constant of variation.

In this problem, varies jointly with and and inversely with , being the constant of proportionality, then:

which three statements are true about all alloys?

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
