12-23.

A moving particle has position at time

*. At*

*, its position is*

*is*

Find 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
