Answer: There is change of $0.9 billion in government expenditures.
Step-by-step explanation:
Since we know that
Marginal propensity to consume tells that the rate at which there is change in consumption due to change in income.
According to our situation, MPC is the change in amount of gross domestic product due to change in government expenditure.
So, it becomes,
Hence, there is change of $0.9 billion in government expenditures.
Given that the subway stations are 930 m apart, the train have to be accerelated for half the distance and then decerelated for the rest of the distance.
Recall that the distance travelled by an object with an initial velocity, u, for a period of time, t, at an accereration, a, is given by
But, we assume that the train accelerates from rest, thus
The maximum speed is attained at half the center of the distance between subway stations (i.e. at distance = 465 m).
Thus, maximum speed = distance / time = 465 / 23.12 = 20.11 m/s.
