Two identical wheels are moving on horizontal surfaces. The center of mass of each has the same linear speed. However, one wheel is rolling, while the other is sliding on a frictionless surface without rolling. Each wheel then encounters an incline plane. One continues to roll up the incline, while the other continues to slide up. Eventually they come to a momentary halt, because the gravitational force slows them down. Each wheel is a disk of mass 1.9 kg. On the horizontal surfaces the center of mass of each wheel moves with a linear speed of 5.40 m/s. (a) What is the total kinetic energy of each wheel

the total distance traveled by the car is

30km + 49km = 79 km .

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

a=d/t

a="triangle"v/t

explanation:

a = acceleration

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
