Find the net gravitational force on each star for each star cluster Let m=mass of the star = 1.99 x 10^30 kg, l=earth to star distance=149.6 x 10^6 km, G=6.67 x10^-11 N m^2/kg^2. Note that the masses of each star are the same. Also, it is advised to use vectors and components. And you can just find the gravitational net force of one of the stars in the shape 1) Triangle

A satellite is placed in an orbit that is twice the radius of the earth. 2.Re b. Re Earth a. Draw a complete free-body diagram for the satellite: What is the gravitational force exerted at this position:

Jacob boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for several rotations. The Ferris wheel has a radius of 13 meters, and when Jacob boards the Ferris wheel he is 19 meters above the ground. Imagine an angle with its vertex at the center of the Ferris wheel that subtends the path Jacob travels. a. Define a function f that expresses Jacob's horizontal distance to the right of the center of the Ferris wheel (in meters) in terms of the number of radians 0 the angle has swept out since the ride started. f(0) = Preview b. Define a function g that expresses Jacob's distance above the ground (in meters) in terms of the number of radians 0 the angle has swept out since the ride started. g(0) = Preview Submit
