<h3>Answer</h3>
m/s^2 (meter per sec square)
Explanation:
acc = change in velocity/time
= distance/time
----------------
time
= m/s
------
s
=m/s^2
Acceleration will be 9.81 if it goes downwards. If it accelerates upwards it will be -9.81m/s^2
The acceleration measures the change in velocity.
Since the acceleration is in the direction opposite to the speed, the velocity eastwards will decrease : its magnitude will first decrease, then it reach 0 m/s, then finally it will increase again.
