Caroline (45 kg) is riding looping roller coaster (radius = 15 meters) at Cedar Point. At the top of the loop she experlences an acceleration of
13.75 m/s/s. Use g310N/kg for the gravitational constant.
Draw a force diagram of the forces acting on Caroline. Determine which force is larger-normal force of gravirational force? Why?
What is the normal force of the seat on Caroline?
Temba is standing in the lunch line 6.4 x 106 m from the center of Earth. Earth’s mass is 6 x 1024 kg. a) What is the acceleration due to gravity? b) When Temba eats his lunch and his mass increases, does this change the acceleration due to gravity?

Now we will examine the case where the planet orbits a star with 8 times the mass of our Sun, but we will say that the dates listed in the diagram above are still accurate for indicating the planet's position as it orbits the new star. What does this imply must be true about about the size of the semimajor axis of the planet in this case compared to the original (aka what is the ratio between the new semimajor axis and the old one)?arrow_forward
