## Homework Statement

This is Pytels Dynamics 2nd edition problem 13.16

**13.16**. Pen P of the flatbed plotter traces the curve y=x

^{3}/80000, where x and y are

measured in mm. When x=200mm, the speed of slider A is 60 mm/s. For this position, calculate

(a) the speed of P; and (b) the normal component of the acceleration of P

## Homework Equations

## The Attempt at a Solution

In part (a) I don't get 108.2 mm/s for the speed. what am I doing wrong?
