A cat is moving at 18 m/s when it accelerates for 2 seconds. What is its acceleration?
vova2212 [387]

Answer: acceleration:4 m/s^{2}

              velocity: 26 m/s

Explanation:

The complete question is written bellow:

<em>A cat is moving at 18 m/s when it accelerates at </em>4 m/s^{2}<em> for 2 seconds. What is his new velocity?  </em>

<em />

In this situation the following equation will be useful:

V=V_{o}+at

Where:

V is the cat’s final velocity (new velocity)

V_{o}=18 m/s is the cat’s initial velocity

a=4 m/s^{2} is the cat's acceleration

t=2 s is the time

Solving the equation:

V=18 m/s+(4 m/s^{2})(2 s)

V=26 m/s This is the cat's new velocity
