(OSU is oregon state university and LBCC is linn-benton community college)
This is a picture of the OSU solar car (which is not nearly as awesome as the LBCC ROV). The car is driving to the right. It is currently speeding up. At this instant: Which way is the angular position vector of the wheels pointing? Please answer with: Up. Down. Right, Left, In to the Page, Out or Not Enough Information to Know Which way is the angular velocity vector of the wheels pointing? Please answer with: Up. Down, Right, Left, In to the Page. Out or Not Enough Information to Know Which way is the angular acceleration vector of the wheels point? Please answer with: Up, Down, Right, Left, In to the Page, Out or Not Enough Information to Know The space shuttle orbits at a constant altitude of 300km. The acceleration due to Earth's gravity at this altitude produces an acceleration that is 9.81m / s2 Slightly less than 9.81m / s2 Much less than 9.81m / s2 Slightly more than 9.81 m / s2 Much more than 9.81 m / s2 Zero There is not enough information given.Explanation / Answer
5.
1. position vector of the wheels r: points toward the right
2. angular velocity vector = w x r = downwards as it is 90 deg to the position vector
3. angular acceleration = left to the position as it is at 180 to the position vector;
7. g' = g * (1-h/R);
where h is the height above the earth's surface and R is the radius of the earth;
thus g' is less than g
