During a plane showcase, a pilot makes circular "looping" with a speed equal to the sound speed (340 m/s). however, the pilot can fall when the acceleration is more than 8g, with g being the gravitational constant. find the radius of the smallest circle that the pilot can take. (hint: think about the centripetal acceleration).

Apossible explanation for a set of facts that can be tested by further investigation is called

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?
