The velocity of a ball as it is thrown up is 20 meters/second. It attains zero velocity after 3. 5 seconds. What is the average acceleration of the ball during its upward flight?.

Cardiac muscle causes movement in the bone.

F= (mass)(acceleration) = mam = 0.25 kgvi = 16 m/st = 2 svf = 0 m/s (since it was put to stop)a=(vf-vi)/ta=(0-16)/2a = 8 m/s^2 (decelerating)f = ma = (0.25 kg)(8 m/s^2)f = 2 nhope this !
