8. A sprinter on a school track team is running north at a velocity of 6.0 m/s. After 5.0 s, she
is running south at 4.0 m/s. Calculate the average acceleration for this interval.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Inside of a windmill or a dam is a that is used to transform one type of energy into electrical energy. a. motor b. generator c. transformer d. power pack
