Answer:
Explanation:
2. Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
3. Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
4. Substituting the equation in 3 into equation in 2 above, we have;
The magnitude of the torque is
Explanation:
The torque exerted by a force acting perpendicular to the arm is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the pivot
In this problem, the force acting on the gymnast is his weight, so the magnitude is given by
where
m = 68 kg is the mass of the gymnast
is the acceleration of gravity
Now we can use the first equation to find the torque, where
d = 2.2 m
And substituting,
