will be the acceleration of a bicycle?

(a) 25m/s

(b) 100m/s

(c) 0.15m/s

(d) 0.25m/s

Answer is 0.25 m/s

Answer 2

D) 0.25m/s²​ will be the acceleration of a bicycle

Step-by-step Explanation:

Given: time = 20s

speed at 20s = 5m/s

To Find: the acceleration of a bicycle

• Finding acceleration of the bicycle

The acceleration of the bicycle is given by

$a = \frac{v - u}{t}$

where $u$ is the initial velocity, $v$ is the final velocity, and $t$ is time.

Therefore, for the bicycle, $u = 0$, $v = 5 \ m/s$ and $t = 20s$

Substituting these values in the above formula, we get

$a = \frac{v - u}{t} = \frac{5 - 0}{20} = 0.25 \ m/s^{2}$

Hence, the acceleration of a bicycle will be 0.25m/s²
