<h2>
Time taken by dryer to come up to speed is 1.625 seconds.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 rad/s
Final velocity, v = 5.2 rad/s
Time, t = ?
Acceleration, a = 3.2 rad/s²
Substituting
v = u + at
5.2 = 0 + 3.2 x t
t = 1.625 s
Time taken by dryer to come up to speed is 1.625 seconds.
To Make I the subject you need to get it by itself. To do this divide both sides by V and t:
I = E/Vt
The
balloon’s potential energy was transformed to kinetic energy as it drops.
Before
the balloon was drop it possessed potential energy but at the moment the
balloon was dropped the potential energy it possessed was transformed into
kinetic energy.
