Answer:
moving up positive acceleration
Explanation:
when moving up as you bounce the ball
the speed changes gradually increasing so according to the equation
acceleration =[speed change ] ÷ period when speed change is positive acceleration is also positive , and an greater value
example speed changes 5m/s within 2 seconds throwing the ball upward
(these are assuming values to explain)
acceleration is 5/2 = + 2.5 m/s^2
so this is an positive acceleration
if negative we call deceleration
