In one of the examples during our class, we found the centripetal
acceleration of the Earth as it
revol ves around the Sun. Now,
compute the centripetal acceleration
of a point on the surface of the Earth
at the equator caused by the rotation
of the Earth about its axis, assuming
that the Earth's radius is 6370 km.
Also compute its angular speed.

What is the angular momentum of the bar about the axle?

What’s #16 asking and how do i solve it?

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?
