On a touchdown attempt a 95.0 kg runningback runs towards the endzone at 4.35 m/s. A 102.0 kg linebacker moving at 6.42 m/s meets the runningback in a head-on collision. If the runningback is moving in the positive direction, and the two players stick together, what is their velocity immediately after the collision?

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

True or false: the revolution of the earth creates day and night as it rotates around the sun

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.
