Activity 1.

1. Calesa is a horse-drawn means of transportation in the Philippines. What is the moment of inertia of a wheel of the calesa having a radius of 0.50 m and a mass of 2.5 kgi rotating about its center? Consider the wheel to be a thin-walled cylinder of negligible length. A 2. The bearing of a machine is a solid sphere having a mass of 250 g and a radius of 2.25 1 cm. Find the moment of inertia of the bearing.

Activity 2

For his early morning exercise, Andee jogged 12 times around a circular track of radius 5.0 m. Find his total distance traveled and his displacement.

Activity 3

Scientists once postulated the existence of a planet called Vulcan to explain Mercury's precession. Vulcan is supposed to be between Mercury and the sun with a solar distance equal to 2/3 that of Mercury. What would be its supposed period?

Activity 4
