B Assuming The Acceleration Is Still 981 Ms2 What Is The Instantaneous Velocity Of The Shuttlecock When It Hits The Ground Show Your Work Below class=

Sagot :

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

From the question we are told

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the

shuttlecock when it hits the ground? Show your work below.

Generally the equation for acceleration  is mathematically given as

[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]

Where

acceleration is still -9.81 m/s2,

Hence,

[tex]V^2-U^2=2(-9.81)*-H[/tex]

Therefore

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]
