A. you might have heard of galileo’s famous experiment to demonstrate that all objects, regardless of their weight and assuming no air resistance, fall at the same acceleration. use newton’s second law of motion to show that for all objects, regardless of their mass, the acceleration due to gravity will be g, which we approximate as 9.8 m/s2.
b. given that the moon has a period of 27.32 days around earth and a radius of orbit which is 60 earth radii, what is the centripetal acceleration of the moon?
c. using newton’s law of gravity, find the acceleration of an object located 60 earth radii away due to the force of gravity from earth.
d.
objects in an elliptical orbit experience a different gravitational force because their distance is constantly changing. using figure 5, which shows the distance between two masses at a certain point in time, how would you calculate the x and y coordinates of the orbiting comet?
hint: put the origin at the location of the sun.
the image shows a commet orbiting aroung a sun in an oval shape. the sun is not in the center of the oval, but closer to the right side
