WebApr 10, 2024 · The body retains its kinetic energy after gaining it during acceleration unless its speed changes. Complete answer: Kinetic energy can only be zero or positive; it cannot be negative. This is due to the fact that kinetic energy is defined as half an object's mass multiplied by its velocity squared. Because mass is a measure of matter, it can ... 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. display off camera on app
