Question

During a 5-second time interval, the average acceleration a , in meters per second squared, of an object with an initial velocity of 12 meters per second is defined by the equation , where v f is the final velocity of the object in meters per second. If the equation is rewritten in the form v f = xa + y , where x and y are constants, what is the value of x ?

Accepted Answer

The correct answer is 5. The given equation can be rewritten in the form , like so: It follows that the value of x is 5 and the value of y is 12.
