Question

a bicycle increases its velocity from 10 km/h in 6 second. Calculate its acceleration.​

Answer 1

Aɴꜱᴡᴇʀ

$\huge{\sf\red{a=3.706{ms}^{2}}}$

Gɪᴠᴇɴ

1. Initial velocity of bicycle = 10kmph
2. Final velocity of bicycle = 15kmph
3. Time interval = 6s

Acceleration of the bicycle

Sᴛᴇᴘꜱ

We know that,

Acceleration is defined as ratio of change in velocity to the time interval.

Converstion :-

1kmph = 5/18mps

15kmph = 4.17mps

10kmph = 2.78mps

Then,

$\begin{lgathered} \boxed{\sf\:a=\dfrac{v-u}{t}}\\ \\ \leadsto\sf\:a=\dfrac{4.17-2.78}{6}\\ \\ \dashrightarrow\:{\sf{\pink{\large{a=3.706\:ms^{-2}}}}}\end{lgathered}$

$\large \tt \bigstar{}Additional \: information$

Acceleration is a vector quantity.

Accelerataion has both magnitude as well as direction.

Acceleration can be positive, negative and zero.
