$\overline{){\mathbf{v}}{\mathbf{=}}\frac{\mathbf{\u2206}\mathbf{x}}{\mathbf{\u2206}\mathbf{t}}}$

**Part A**

$\mathit{v}\mathbf{=}\frac{\mathbf{(}\mathbf{200}\mathbf{}\mathbf{-}\mathbf{}\mathbf{0}\mathbf{)}\mathbf{}\mathbf{m}}{\mathbf{(}\mathbf{4}\mathbf{-}\mathbf{1}\mathbf{)}\mathbf{}\mathbf{s}}$

The figure shows a graph of actual position-versus-time data for a particular type of drag racer known as a "funny car." (Figure 1)

Figure 1 of 1

**Part A**

Estimate the car's velocity at 2.0 s.

Express your answer to one significant figure and include the appropriate units.

**Part B**

Estimate the car's velocity at 4.0 s.

Express your answer to two significant figures and include the appropriate units.
