An arrow is launched vertically upward from a crossbow at 98.2 m/s. Ignoring air friction, what is its instantaneous acceleration 4.20 s into the flight?

• Physics -

The acceleration will be -g, which is -9.8 m/s^2, at all times. It is directed downward.

It makes no difference what the initial speed or the elapsed time is. Those numbers are put there to confuse you.
