The average velocity of the Batman is 0.722 m/s North-East.

What is average velocity?

Average velocity can be defined as the ratio of the total displacement to the total time of a body.

To calculate the average velocity of Batman, we use the formula below, first, we need to calculate the resultant displacement of the Batman.

  • D = √[(d₁-d₃)²+ (d₂)²]............... Equation 1

Where:

  • d₁  = first displacement of the Batman = 6 m North
  • d₂ = second displacement of the Batman = 3 m East
  • d₃ = third displacement of the Batman. = 4 m south

Substitute these values into equation 1

  • D = √[(6-4)²+3²]
  • D = √(2²+3²)
  • D = √(4+9)
  • D = √13
  • D = 3.61 m North-East.

To calculate the average velocity, we use the formula below.

  • V = D/T............ Equation 2

Where:

  • D = 3.61 m North-East
  • T = total time = 15 s

Substitute these values into equation 2

  • V = 3.61/5
  • V = 0.722 m/s North- East.

Hence, the average velocity of the Batman is 0.722 m/s North-East.
