12-23.

A moving particle has position . At

*, its position is*

*is*

What is the acceleration vector at

?The acceleration vector can be obtained by taking the derivative of each component of the velocity vector.

For what time

does the velocity vector have a slope of? Divide the vertical component by the horizontal component of the velocity vector. This should equal
