Answer:
The torque needed is 46.08 Nm
Explanation:
Given;
angular velocity, ω = 12 rad/s
time of motion, t = 0.5 s
length of the baton, r = 0.8 m
mass of the baton, 0.5 kg
The torque needed to reach the angular velocity is given by;
τ = F x r
where;
F is the centripetal force of the baton
r is the length of the baton = radius of the circular motion of the baton
Torque is given by;
Therefore, the torque needed is 46.08 Nm
<h2>Answer:Displacement</h2>
Explanation:
Potential energy is present in a spring because the spring is elongated and some work is done it to elongate it.
The elastic potential energy present in a spring is given by
where is the spring constant.It may vary from spring to spring and
is the displacement of the spring from its equalibrium position.
It is evident from the equation that potential energy in the spring increases as increases.
