A stone is thrown upward on the moon with its height (in feet) after t seconds given by h(t) = 20 − 5t2. Include units with your answer.
a) What is the acceleration of the stone at 2 seconds?
b) What is the average velocity of the stone between 1 and 3 seconds?
c) What is the instantaneous velocity of the stone at 2 seconds?
d) With what velocity does the stone hit the ground?
Note: I think there might be a mistake in the question as the height function implies to initial velocity, but the question mentions that the stone is thrown upward.
Still, I have done whatever the question asked me to do
