Which of the following statements about this lab are true? You should take the average of the acceleration data in an appropriate time interval. Logger ProTM will report the angle, angular velocity and angular acceleration of the big wheel, not the rotation sensor. If the large wheel is rotating clockwise, the friction from the large wheel's bearings will cause a clockwise angular acceleration. We assume the sensor wheel is massless and does not affect the accelerations measured.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
