Can anyone please help me out with these two questions? 1. Starting from rest, a car travels 1350m in one minute. It accelerated at 1m/s2 until it reached its cruising speed. Then it drove the remaining distance at constant velocity. What was its cruising speed? All I did was I divided 60s into 1350m and my result was 22.5. Is this the average velocity? 2. A satellite is in circular orbit 600km above the Earth's surface. The acceleration of gravity is 8.21m/s2 at this altitude. The radius of the Earth 6400km. Determine the speed of the satellite and the time to complete the orbit around the Earth. I have no idea how to go about this problem. Is this centripetal acceleration?
