Answer:
[tex]t=4.6\times 10^{-4}\ s[/tex]
Step-by-step explanation:
We have,
Initial velocity of arm club is 23 m/s
Acceleration is 100000 m/s²
It is required to find the time taken by it to take the arm-club to get to 23 m/s. It means v = -23 m/s. It is based on the equation of kinematics such that :
[tex]v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{-23-23}{100000}\\\\t=4.6\times 10^{-4}\ s[/tex]
So, the time taken by it is [tex]4.6\times 10^{-4}\ s[/tex].
