A 1500 kg car speeds up from zero to 3.0 ms. it has kinetic energy of 6750 J at top spreed. True or False?
Andrew [12]

Answer:

True

KE = 1/2 mv^2

m = 1500 kg

v = 3 m/s

KE = 1/2 (1500 kg)(3 m/s)^2

KE = (750 kg)(9 m^2/s^2)

KE = 6,750 J

How do i get the anser on here please go as in depth as posible
Pachacha [2.7K]

as you should already know to get the inverse of any expression, we start off by doing a <u>quick switcheroo</u> on the variables, and then solve for "y".

\bf \stackrel{f(x)}{y} = \cfrac{x}{x-1}\implies \stackrel{switcheroo}{x=\cfrac{y}{y-1}}\implies x(y-1)=y\implies xy-x=y \\\\\\ -x=y-xy\implies -x=\stackrel{\textit{common factor}}{y(1-x)}\implies \cfrac{-x}{1-x}=y \\\\\\ \cfrac{x}{-(1-x)}=y\implies \cfrac{x}{x-1}=\stackrel{f^{-1}(x)}{y}
