The International Space Station orbits the earth at an altitude of 400 km and circles the earth in 90 minutes. Assume the speed of the orbiting Space Station remains constant.

a) What is the angular speed, in rad/s, and the linear speed, in km/h, of the Space Station while in orbit?

b) What is the acceleration of the Space Station, in m/s2 , expressed in normal and tangential coordinates?
