Starting from stationary motion round paddles in bicycle to attain a velocity of 10m/s in 30s . Calculate the acceleration of the bicycle
Answers
✬ Acceleration = 0.3 m/s² ✬
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.
v = u + at
10 = 0 + a 30
10 = 0 + 30a
10 = 30a
10/30 = a
0.3 m/s² = 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) ★
a = (10 – 0/30) m/s²
a = (10/30) m/s²
a = 0.3 m/s²

★ Two other laws of motion ★
➛ s = ut + 1/2at²
➛ v² = u² + 2as
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:-
According to question:-
On putting the given values in the formula, we get
❝ Hence, the acceleration of the bicycle is 0.3 m/s² ❞
