Question

A cockroach moves rectilinearly such that, after sometime t subscript 0 end subscript let its (instantaneous) velocity be equal to its average velocity over that time. Referring to the s minus t graph as shown in the figure for the motion of the cockrach, find the average velocity of the cockroach over the time t subscript s end subscript.

  1. 0.67 m/s    
  2. 1.67 m/s    
  3. 2.67 m/s    
  4. 3.67 m/s    

The correct answer is: 0.67 m/s
