A 75 kg snowboarder slides up a frictionless rail to a height of 1.75 m high and slides across it at 2.50 m/s. How much kinetic energy did he have before sliding up the rail?

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.
