Answer:
B is the answer for the question
From the data given, the final velocity is equal to 6 m/s. This is from the equation a = vf - vo / t. The second kinetic equation to be used to determine the distance traveled is 2ax = vf2 - vo2. Substituting, 2*0.6*x = 6^2 - 3^2 ; x then is equal to 22.5 meters
Savings is inversely related to expenditure when the income is constant. <span>A more technical example is current is inversely proportional to the resistance in the circuit provided the voltage is constant. When the resistance is high, current is low, and vice-versa.</span>
