Question

A scootexist increases its speed from 10mls to 20mls in
IO sec. Find its acceleration -

Please answer me ​

Answer 1

ɢɪᴠᴇɴ :-

• Initial velocity (u) = 10m/s
• Final velocity (v) = 20m/s
• Time taken (t) = 10 seconds

ᴛᴏ ғɪɴᴅ :-

• Acceleration (a)

sᴏʟᴜᴛɪᴏɴ :-

On using the 1st equation of motion, we get,

➦ v = u + at

Put the above given values in it, we get,

➭ 20 = 10 + a×10

➭ 20 - 10 = 10a

➭ 10a = 10

➭ a = 10/10

➭ a = 1 m/s²

Hence,

• Acceleration (a) = 1 m/s²

Answer 2

Answer:

Explanation:

Coorect Question,

A scooterist increases its speed from 10 m/s to 20 m/s in  10 sec. Find its acceleration.

Solution,

Here, we have

Initial velocity, u = 10 m/s

Final velocity, v = 20 m/s

Time taken, t = 10 seconds

To Find,

Acceleration, a = ?

According to the 1st equation of motion,

We know that,

v = u + at

So, putting all the values, we get

⇒ v = u + at

⇒ 20 = 10 + a × 10

⇒ 20 - 10 = 10a

⇒ 10 = 10a

⇒ 10/10 = a

⇒ a = 1 m/s²

Hence, the acceleration of the scooterist is 1 m/s².
