A day on a distant planet observed orbiting a nearby star is 31.7 hours. Also, a year on the planet lasts 79.5 Earth days.* Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth.
Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth.
Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.
