An insect of mass m walks with constant speed v0 in a circular path of radius b on a rotating disk with constant angular velocity w. Describe the motion in a coordinate system fixed to the turntable. Calculate the acceleration r'' of the insect with respect to the outside. In particular, calculate r'' for the cases: v0 = bw and v0 = −bw. Note that in the second case the insect is stationary with respect to the outside.

Analyzing circular motion at constant speed is an important next step after you've developed an ability to explain motions with constant acceleration (like free fall). The peculiarity of circular motion at constant speed is that the magnitude of the acceleration is constant, but the direction of the acceleration vector rotates so that it always points to the center of the circle. It's completely different than "free fall", where the acceleration's direction points down and doesn't rotate. Rotating acceleration is illustrated in the top figure. Two velocity vectors are shown: V₁ and V2. They indicate the velocities at the two ends of an arc. They have the same length v, which matches the constant speed idea. The direction changes as the ball moves around. When you subtract one vector from the other, the difference is the "velocity change vector". It always points towards the center of the circle from the middle of the arc. The "centripetal acceleration" has the magnitude a centripetal…

Assume that we have a distant Star-Planet system with no other planets and the Star is the same as the Sun and the planet is the same as the Earth. This is called an "Earth analog system or "Earth twin". The masses and the orbits are the same except you can assume a perfectly circular orbit. A) Calculate the equation for the orbital velocity of a planet on a circular orbit. To do this use the equation for average speed: distance=rate x time. In a circular orbit, the speed is always the same, so you can use a time that is one full orbital period (1 year). What is the distance that a planet on a circular orbit travels in this time? Calculate the speed of the Earth twin in meters/second. Mass of the sun: 2 x 1030 kg. Mass of the Earth: 5.97 x 1024kg (Note: I think I understand how to use the distance= rate x time, but I'm not sure what to input for rate in this situation. I am also not sure how to calculate the speed of the Earth twin)
