Q. The distance from the Earth to Polaris is approximately 7.576 10^18 m. How long would it take to disappear from our vision if it were to burn out today? Answer in units of years

Q. Two blocks are arranged as shown. The pulley can be considered to be massless, and friction is negligible. M1 is five times more massive than M2. One force acts on the hanging mass, but the net force acts on both masses. Once you have the acceleration, you can calculate the distance.
