A light-rail commuter train draws 600 A of 675 V DC electricity when accelerating. a) What is its power consumption rate? b) How long does it take to reach 20 m/s starting from rest if its loaded mass is 3.5×104 kg, assuming 95 % efficiency and constant power? c) What is the average acceleration of the train?
Conceptual Example 13 provides useful background for this problem. A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 125 kg · m2. When one person is standing on the carousel at a distance of 1.5 m from the center, the carousel has an angular velocity of 0.6 rad/s. However, as this person moves inward to a point located 0.734 m...

When one person is standing on the carousel at a distance of 1.5 m from the center, the carousel has an angular velocity of 0.6 rad/s. However, as this person moves inward to a point located 0.973 m from the center, the angular velocity increases to 0.8 rad/s. What is the person's mass?
