Acceleration = 0.3 m/

Explanation:

Given:

  • A bicycle is in stationary position (u) = 0 m/s
  • Bicycle attains a velocity (v) of 10 m/s.
  • Time (t) by bicycle is 30 seconds.

To Find:

  • What is the acceleration of the bicycle ?

Formula to be used:

  • First law of motion
  • v = u + at

Solution: Here, we have

  • v = 10 m/s , u = 0 m/s , t = 30 seconds.

Put the values on formula.

\implies{\rm } v = u + at

\implies{\rm } 10 = 0 + a \times 30

\implies{\rm } 10 = 0 + 30a

\implies{\rm } 10 = 30a

\implies{\rm } 10/30 = a

\implies{\rm } 0.3 m/ = a

Hence, the acceleration of the bicycle is 0.3 m/s².

[Another Method]

To find acceleration there is an another formula

Acceleration = (v u/t)

\implies{\rm } a = (10 0/30) m/

\implies{\rm } a = (10/30) m/

\implies{\rm } a = 0.3 m/

GIVEN:

  • Initial Velocity (u) = 0 m/s (Bicycle starting from stationary motion)
  • Final velocity (v) = 10 m/s
  • Time taken (t) = 30 seconds

TO FIND:

  • What is the acceleration of the bicycle ?

SOLUTION:

Let the acceleration of the bicycle be 'a' m/s²

We know that the formula for finding the acceleration of the bicycle is:-

\bf{\star \: Acceleration = \dfrac{Final \: Velocity - Initial \: Velocity}{Time \: taken} \: \star}

According to question:-

On putting the given values in the formula, we get

\rm{\dashrightarrow a = \dfrac{10-0}{30}}

\rm{\dashrightarrow a = \cancel\dfrac{10}{30}}

\large\bf{\dashrightarrow \star \: a = 0.3 \: m/s^2\: \star}

Hence, the acceleration of the bicycle is 0.3 m/
