Answer: its mechanical energy
Explanation:
Answer:
t = 0.0735 m
Explanation:
Angular acceleration of the flywheel is given as

now after t = 8 s the speed of the flywheel is given as



now rotational kinetic energy of the wheel is given as




now we have



The difference between the above velocities is that they exist in opposite direction of each other. or it can be said that they are negative vectors of each other.
Answer:
The graph appears to be in error.
The actual figure appears to be a rhombus with sides of 5 and 15 with a height of 5
The work done (F * S) is the area of the rhombus
1/2 * (5 +15) * 5 = 50 J
