Answer:
C. Why you must push harder to move a car farther.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Hence, Newton's 2nd Law explains why you must push harder to move a car farther because of its mass. Thus, it is important to increase the force that the engine provides and decrease the mass of the car.
Answer:
Explanation:
Since , we calculate the resistance rate by deriving this formula with respect to time:
Deriving what is left (remember that ):
So we have:
Which for our values is (the rate of <em>I(t)</em> is decreasing so we put a negative sign):
