Mr. Anderson shoots an arrow straight up into the air. The arrow leaves her

bow at 1.2[m] above ground, and reaches a height of 95 feet above ground.
It then falls down and penetrates 14 inches into the ground. Find:
a) The velocity of the arrow just before reaching the ground.
b) The acceleration of the arrow inside the ground (assume constant).
c) The time it takes the ground to stop the arrow.
d) The direction of the acceleration.
