In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.
Let's start with the basic sine function, f (t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units.

The formula of the kinetic energy is: where m is a mass of the object, v is speed of the object at the moment of time. So we have: The answer is 2000 Joules.
