In an experiment, a bump car is allowed to travel freely from one end to another in a meter stick. When it hits one end, the car bounces back 6 meters and then move forward again. On each bounce, it moves back 2/3 of the distance is it previously , traveled. a.) determine the distance covered by the bump car from the head wall after 4 bounces. b.) solve for the total distance traveled by the car after 5 bounces.

q3) You are now in 20 years old. You are disappointed with the current situation. So, you decide to leave to the future of Earth. You plan a space journey for 5 years(go in 2.5 years and back in 2.5 years.) with a constant speed   relative to Earth. If you wish to reach the Earth after 100 years when you are 25 years old, how fast the speed,  you need to set for your spaceship? (Give your answer in 5 significant figures)
