Acar of mass 1800 kg is traveling east at 60 km/hr approaching an intersection. a large truck of mass 2400 kg is approaching the same intersection traveling north at 60 km/hr. after the collision, the car and the truck become tangled and move as a single object. assume that it’s a very slick road so that there is no friction between the vehicles and the ground. use only mks units.
is the collision between the cars elastic or inelastic?

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.
