**The figure shows a graph of actual position-versus-time data for a particular type of drag racer known as a "funny car."**

**Estimate the car's velocity at 2.0s**

Equation:

*v = m/s*

I thought I knew how to solve this, and I made a tangent line at the curve and 2s, and when I do the slope at different points on the tangent I keep getting somewhere in the field of 50m/s. However, it keeps telling me I'm wrong. What should I be doing differently?

Thank you for your help!
