Question

Suppose Batman travels 6 m North, 3 m East, and then 4 South. The entire trip takes 15 s. what is his average velocity

Answer 1

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.
