Answer: Always accelerates in a downward direction
Explanation: Gravity is pulling the ball downward
Answer:
51.2 J, 86.2 J, 137.4 J
Explanation:
The kinetic energy of the ball is given by:

where
m = 0.40 kg is its mass
v = 16 m/s is its speed
Substituting,

The potential energy of the ball is given by

where
m = 0.40 kg
is the acceleration of gravity
h = 22 m is the heigth of the cliff
Substituting,

Finally, the total mechanical energy is the sum of the kinetic energy and the potential energy:
