If a cars velocity changes from 25 m/s to 15 m/s in 2 s, then what is its acceleration

Explanation:

Formula

final velocity - initial velocity

divided by what given acceleration or time

in this casi we're looking for acceleration so we cross it out

15m/s-25m/s divided by

2s

=-10m/s/2s

=2.5m/s square

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
