The kinetic energy of a moving object, E joules, is directly proportional to the square
of its speed, v m/s. If the speed of the moving object is halved, calculate the
corresponding change in kinetic energy of the object.

Adepartment store purchases screen-printed t-shirts at a cost of $5 per shirt. they mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.
