- Thinking Mathematically: Explore the quantitative dependencies of the acceleration upon the speed and the radius of curvature. Then answer the following questions. Choose the right answer in the parenthesis. For the same speed, the acceleration of the object varies (directly, inversely) with the radius of curvature. For the same radius of curvature, the acceleration of the object varies i(directly, inversely) with the speed of the object. As the speed of an object is doubled, the acceleration is (one-fourth, one-half, two times, four times) the original value. 4. As the speed of an object is tripled, the acceleration is (one-third, one-ninth, three times, nine times) the original value.You are on the plane neptune and want to determine the acceleration due to gravity, g. You have a stopwatch and a toy gun that can launch a ping pong ball vertically upwards with an initial velocity of 7.5 m/s. Describe, in words, how you would perform an experiment to determine the acceleration due to gravity. Be sure to describe the variables you would measure, the equations you would use and the assumptions you would make. Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Thanks!Again, consider the off-road vehicle shown in the picture.
