A RED toy car of mass 4.7 kg, hits BLUE toy car, with mass 1.2 kg, head-on. The blue car originally had a velocity of -15 m/s. After the two cars collide, they stick together and stop. What was the Red car's original velocity?

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.)

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
