A car travels around a curve with a constant speed What if anything happens to the velocity of the car in this process? 1. its magnitude changes 2. its direction changes 3. it remains constant I need help with this part b

If the earth revolves around the sun at a constant distance of 1.50 x 1011 m, what is the centripetal acceleration of the sun if one earth year is 365 days?   a. 4.0 x 10-3 m/s2   b. 3.0 x 10-3 m/s2   c. 6.0 x 10-3 m/s2   d. 5.0 x 10-3 m/s2   e. 2.0 x 10-3 m/s2

A car on a highway is heading toward a cloverleaf interchange with a circular curvature or Radius=50 m, traveling at a steady speed of 14m/s. A) determine the position and velocity of the vehicle at points A and B. B) determine the vector components and direction of the average acceleration during the trip from a to b. Include a sketch of the vector showing it's orientation. SPeciffy the direction between -180 degrees and 180 degrees as measured from the +x axis.
