A980-kg sports car collides into the rear end of a 2300-kg suv stopped at a red light. the bumpers lock, the brakes are locked, and the two cars skid forward 2.6m before stopping.the police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. what was that speed?

We know that the law of conservation of energy states that energy can not be created or destroyed. it only changes form. consider this energy transformation diagram. assume that the energy input in this case is chemical potential energy and the useful energy output is kinetic energy, specifically a small fan to keep you cool. the diagram also shows how to calculate the efficiency of the fan. if the law of conservation of energy holds true, explain why the efficiency of the fan is not 100%.

Aprojectile is shot upward from the surface of earth with an initial velocity of 96 meters per second. use the position function below for free-falling objects. what is its velocity after 5 seconds? after 10 seconds? (round your answers to one decimal place.)
