Compute all parts of given problem:
Problem: A circumpolar star has an altitude over the horizon of 4 degrees 12' at west-to-east transit and 51 d 30' at east-to-west transit (how does it transit twice?)
Part A: What is the latitude of the observer?
Part B: What is the declination of the star? Assume atmospheric refraction has been accounted for.
Please show clear steps and work for points. Thanks!
A lowly high diver pushes off horizontally by a speed of 2.77 m/s from the edge of a platform that is 10.0 m above the surface of the water. (a) At what horizontal distance from the edge of the platform is the diver 0.885 s after pushing off?
Use the work-energy theorem to find out how high it will be when its speed has been reduced to half of its initial value. Please provide step-by-step process.
