Question

Suppose you increase your walking speed from 6s to 12 m/s in a period of 2 s. What is acceleration

Answer 1

As we know that acceleration is given as

`a = (v_f - v_i)/(t)`

here we know that

`v_i = 6 m/s`

`v_f = 12 m/s`

`\Delta t = 2 s`

now we will have

`a = (12 - 6)/(2)`

`a = 3 m/s^2`

so acceleration will be 3 m/s^2
