Question

- Suppose you increase your running speed from 7 m/s to 9 m/s in a period of 2 s. What is

Answer 1

Step-by-step explanation:

• Initial velocity (u) = 7 m/s
• Final velocity (v) = 9 m/s
• Time taken (t) = 2s

$\dashrightarrow \quad \rm {a = \dfrac{v -u}{t} }$

• a denotes acceleration
• v denotes final velocity
• u denotes initial velocity
• t denotes time

$\dashrightarrow \quad \rm {a = \dfrac{9 -7}{2} \; m \: s^{-2}}$

$\dashrightarrow \quad \rm {a = \dfrac{2}{2} \; m \: s^{-2}}$

$\dashrightarrow \quad \underline{\boxed{\bf {a = 1 \; m \: s^{-2}}}}$ (Answer)
