Answer 1

Qᴜᴇsᴛɪᴏɴ :

➥ A racing car has a uniform acceleration of 4m/s^2 what distance does it cover in 10 seconds?

Aɴsᴡᴇʀ :

➥ Distance (s) = 200m

Gɪᴠᴇɴ :

➤ Acceleration (a) = 4 m/s²

➤ Time (t) = 10 sec

➤ Initial velocity (u) = 0

Tᴏ Fɪɴᴅ :

➤ Distance (s) = ?

⠀

❏ According To Given Question

⠀

↗ From the second equation of motion.

❊ As we know that the formula for finding the distance (s) is ፦

$\bf{ : \implies s = ut + \dfrac{1}{2} \ {at}^{2} }$

⤵ On putting the given value in the formula, we get

$\sf{ : \implies 0 \times 10 + \dfrac{1}{ \cancel{ \: 2 \: }} \times \cancel{ \: 4 \: } \times10 \times 10 }$

$\sf{:\implies 0 + 2 \times 10 \times 10}$

$\sf{: \implies \underline{\overline{\boxed{\purple{\bf{\:\: s = 200 \: m\:\:}}}}}}$

Hence, the required distance is 200m
