Question

A scooter travelling at 10 m/s speed up to 20 m/s in 4 sec. Find the acceleration of scooter​

Answer 1

Gɪᴠᴇɴ :-

• Initial velocity (u) = 10 m/s
• Final velocity (v) = 20 m/s
• Time taken (t) = 4 s

ᴛᴏ ғɪɴᴅ :-

• Acceleration (a)

sᴏʟᴜᴛɪᴏɴ :-

On using first equation of motion , we get,

➭ v = u + at

➭ 20 = 10 + a × 4

➭ 20 - 10 = 4a

➭ 4a = 10

➭ a = 10/4

➭ a = 2.5 m/s²

Hence,

• Acceleration (a) = 2.5 m/s²

Answer 2

Answer:

HERE IS UR ANSWER DEAR,

GIVEN:

initial velocity (u) =10m/s

final velocity (v) =20m/s

time (t) = 4s

TO FIND:

acceleration (a)

FORMULA :

a = (v-u ) / t

SOLUTION:

a = ( 20-10) / 4

a = 10 / 4

a = 2.5 m/s²
