For each of the cases described below, sketch and label the total acceleration vector, the radial acceleration vector, and the tangential acceleration vector.
- A car is accelerating from 55 km/h to 70 km/h as it rounds a curve of constant radius.
- A car is going a constant 65 km/h as it rounds a curve of constant radius.
- A car slows down while rounding a curve of constant radius.
