Let us say that v is the
tangential velocity of the object, a to be the centripetal (which acts towards
the center of the circle) acceleration and F as the centripetal force, r to be
the radius of the circle and m is mass of the child. <span>
a = v^2 / r
F = ma = mv^2/r
Applying the given values to the equation:
F=30*(5^2/5) => 30*(25/5) => 30*5 => 150 Newtons</span>
Now work is Force times
distance, the distance is simply the circumference of the circle.
d = C = 2 * pi * r = 2 *
pi * 5 = 10π m
W = F * d = 150 N * 10π
m
<span>W = 1500π J = 4712.39 J</span>
Answer:
True
Explanation:
Just as Isaac Newton says, "For every action, there is an equal and opposite reaction."
And the answer is True, It has the most of <span>complex level of organization within large organisms, such as elephants, is the organ system.

Answer:
Velocity- v=10m/s south Speed- v=10m/s
Explanation:
the salar measurement of how fast an object is moving.
Velocity- v=10m/s south :
The vector rate of change of position.
Speed- v=10 m/s : the salar measurement of how fast an object is moving.
