I don't understand how to solve these, so I would really appreciate it if you showed the work along with the answers and the conversions. Thank you very much! 1. You see a lightening bolt in the sky. You hear a clap of thunder 3 seconds later. Sound travels at a speed of 330 m/s. Assuming you see the lightening bolt instantly, how far away was the lightening? 2. If a river current is 8.0 m/s and a boat is traveling 10.0 m/s against the current, what is the boat's speed relative to the river bank? (Pythag theorem, right?) 3. A rocket ship is moving through space at 1000 m/s. It accelerates in the same direction at 4 m/s squared. What is its speed after 1 minute and 40 seconds? 4. The propulsion system on the rocket ship described in the last problem is tested. Its rockets are fired and the ship accelerates from rest at 5m/s squared for 2 minutes. How does the ship's final velocity compare to the ship's initial velocity in the last problem? 5. Light from a star travels to Earth in a straight line at a constant speed of 300,000 km/s. What is the acceleration of the light?
