Two bumper cars are driven straight toward each other. The mass of bumper car 1 is 110.0 kg, and the mass of bumper car 2 is 170.0 kg. Bumper car 1 has a velocity of 1.5m/s and bumper car 2 has a velocity
of -2.0 m/s. The final velocity of bumper car 1 is -2.75
m/s.

What is the velocity of bumper car 2 immediately after the collision?
Your answer should have two significant figures.

Which type of bond is found between the atoms of a molecule? a. metallic b. delocalized electron c. covalent d. ionic

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

The amount of potential energy possessed by an elevated object is equal to what?
