Halley's comet orbits the sun about every 75 years due to the gravitational force the sun provides. Compare the gravitational force between halley's Comet and the sun when the comet is at aphelion (its greatest distance from the sun) and d is about 4.5 x 10^10 m to the force at perihelion (or closest approach), where d is about 5.0 x 10^10 m. B) In part A, what is the comet's acceleration a) at aphelion? b) at perihelion? (M of the sun=1.99 x 10^30) Please help!!!

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
