WebSince we know that energy is conserved, we can subtract this energy value from the initial potential energy to find the value of kinetic energy. E k 2 = E p 1 - E p 2 = 5. 5 - 3. 3 = 2. 2 J. In order to find the ball's speed at position 2, we will use the kinetic energy formula and put in the known variables.

WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent … WebLet's consider a situation where an object is attached to a spring and is moved from an initial position to a final position. The conservation of energy equation for the object only system is: K E i + … where KEi is the initial kinetic energy, PEi is the initial potential energy, KEf is the final kinetic energy, PEf is the final potential energy, Wnc is the work done by non …

WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s.
