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. WebSep 12, 2024 · Figure 15.3.1: The transformation of energy in SHM for an object attached to a spring on a frictionless surface. (a) When the mass is at the position x = + A, all the energy is stored as potential energy in the spring U = 1 2 kA 2. The kinetic energy is equal to zero because the velocity of the mass is zero.

In a single event, the sum of the two types of mechanical energy is … In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes. In all real systems…
