Multiple Choice

Calculate the velocity during the time segment from 1 - 3 sec.

• + 0.4 m/s, meaning to the right

  $$\frac{\left(1\ -\ 0.2\right)}{\left(3-1\right)}=\ +0.4\ \frac{m}{s}$$

• + 0.3 m/s, meaning to the right

  
  $$\frac{\left(1-0\right)}{\left(3-1\right)}=+0.3\ \frac{m}{s}$$
  

• + 0.5 m/s, meaning to the right

  
  $$\frac{\left(1.5-0\right)}{\left(3-0\right)}=\ +0.5\ \frac{m}{s}$$
  

• 
  + 2.4 m/s, meaning to the right
  $$\frac{\left(3-1\right)}{\left(1-0.2\right)}=+2.5\ \frac{m}{s}$$
