1- A 300 ? mass is attached to
a solid 40 ?? long string the other end of which is secured to the
ceiling. The mass is given an initial speed which makes it swing
around a circular path in the horizontal plane without changing its
speed and without changing its height. The object completes 2
revolutions in 2 seconds.

4 10 points You send a flash of light toward the Moon. It bounces off a mirror and returns to you. You measure the time between when you sent the flash and when it returns to you and find that the whole process took 2.0 seconds. The distance to the Moon is (state your answer in kilometers and list the answer with at least three significant figures.) You can use 3x108 m/s as the speed of light (feel free to...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...
