Question

Jenny runs from 2 m/s to 8 m/s in 2 seconds. What is Jenny’s acceleration?

Answer 1

$\sf\underline{Answer:}$

Initial velocity (u) = 2 m/s

Final velocity (v) = 8 m/s

Time = 2 seconds

$a = \frac{v - u}{t}$

$a = \frac{8 - 2}{2}$

$a = \frac{6}{2} = 3m/ {s}^{2}$

Have a good day!

Answer 2

Answer:

Initial velocity (u) = 2 m/s

Final velocity (v) = 8 m/s

Time = 2 seconds

a = \frac{v - u}{t}a=tv−u

a = \frac{8 - 2}{2}a=28−2

a = \frac{6}{2} = 3m/ {s}^{2}a=26=3m/s2
