Answer:
The acceleration of a bike is 2.34 m/s².
Explanation:
Given that,
Velocity = 38 km/hr
Time = 4.5 s
We need to calculate the acceleration
Using equation of motion
[tex]v = u+at[/tex]
[tex]a=\dfrac{v-u}{t}[/tex]
Where, v = final velocity
u = initial velocity
t = time
Put the value in to the formula
[tex]a=\dfrac{0-38\times\dfrac{5}{18}}{4.5}[/tex]
[tex]a=-2.34\ m/s^2[/tex]
Negative sign shows the deceleration.
Hence, The acceleration of a bike is 2.34 m/s².
