Answer:
F = M ω^2 R is the centripetal force on the ball
f = 7 / 10 = .70 / sec revolutions / sec
ω = 2 pi f = 4.40 / sec
ah = F / m = 4.4^2 * 2 = 38.7 m/s^2
horizontal acceleration = 38.7 m/s^2
vertical acceleration = 9.80 m/s^2
a = (38.7^2 + 9.8^2)^1/2 = 39.9 m/s^2 total acceleration
Work = (force) x (distance)
Work = (22 N) x (16 m)
<em>Work = 352 Joules</em>
Landforms result from a combination constructive and destructive forces.

The energy stored in motion is called kinetic energy.
All of the electromagnetic energy radiated from the sun (and from
other stars) is the product of nuclear fusion in its core.
