- Answer a and cA car on a highway is heading toward a cloverleaf interchange with a circular curvature or Radius=50 m, traveling at a steady speed of 14m/s. A) determine the position and velocity of the vehicle at points A and B. B) determine the vector components and direction of the average acceleration during the trip from a to b. Include a sketch of the vector showing it's orientation. SPeciffy the direction between -180 degrees and 180 degrees as measured from the +x axis.Analytical Model Tutorial The 20-g centrifuge at NASA's Ames Research Center in Mountain View, California, is a horizontal, cylindrical tube of length 58.0 ft. Another 20-g centrifuge of length L = 59.0 ft is represented in the figure below. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 29.5 ft away. Determine the rotation rate, in revolutions per second, required to give the astronaut a centripetal acceleration of 20.0g. L/2 Part 1 of 4 - Conceptualize: Look carefully at the figure and imagine you are the astronaut sitting in the seat at the far right. As the centrifuge rotates, you are experiencing an acceleration toward the center of the device. The faster the centrifuge spins, the larger is that acceleration. The problem is asking for a rotation rate, measured in revolutions per second. Because the period of circular motion is the number of seconds per revolution, we see that the rotation rate will be the inverse of the period. 1 rotation…
