Answer:
The rotational kinetic energy of the rotating wheel is 529.09 J
Explanation:
Given;
moment of inertia I = 0.35kg⋅m²
number of revolutions = 35.0
time of revolution, t = 4.00 s
Angular speed (in revolution per second), ω = 35/4 = 8.75 rev/s
Angular speed (in radian per second), ω = 8.75 rev/s x 2π = 54.985 rad/s
Rotational kinetic energy, K = ¹/₂Iω²
Rotational kinetic energy, K = ¹/₂ x 0.35 x (54.985)²
Rotational kinetic energy, K = 529.09 J
Therefore, the rotational kinetic energy of the rotating wheel is 529.09 J
