The kinetic energy of flywheel of a stationary engine is 120J.
<u>Explanation:</u>
Key Terms:
- torque: A rotational or twisting effect of a force; (SI unit newton-meter or N m; imperial unit foot-pound or ft-lb)
- inertia: The property of a body that resists any change to its uniform motion; equivalent to its mass.
- angular velocity: A vector quantity describing an object in circular motion; its magnitude is equal to the speed of the particle and the direction is perpendicular to the plane of its circular motion.
Here , angular acceleration = 2
Angular velocity w = Angular acceleration × time
∵ Acceleration is 2 rad per second sq. So , time is 1 sec.
⇒ Angular velocity (w) =
⇒ Angular velocity (w) =
Now, kinetic energy ⇒
⇒
⇒
⇒
∴ The kinetic energy of flywheel of a stationary engine is 120J.
Displacement is the distance from the final placement of the object from the initial point. So, since the swimmer started and ended in the same spot, it is zero.
Therefore your correct answer is:
A: 100m swimming 0 displacement
