A cat accelerates from rest to 10m/s when it sees a dog. This takes 2 seconds. What was the acceleration of the cat

Respuesta :

Answer :

Acceleration of the cat is [tex]a=5\ m/s^2[/tex]

Explanation:

It is given that,  

Initial speed of the cat, u =0 (at rest)

Final speed of the cat, v = 10

Time taken, t = 2 s

Let a is the acceleration of the car. We know that the rate of change of velocity of an object is called its acceleration. Mathematically, it is given by :

[tex]a=\dfrac{v-u}{t}[/tex]

[tex]a=\dfrac{10-0}{2}[/tex]

[tex]a=5\ m/s^2[/tex]

So, the acceleration of the cat was [tex]5\ m/s^2[/tex]. Hence, this is the required solution.

The acceleration of the cat to reach its maximum velocity of 10 m/s in 2 seconds is 5m/s².

What is the acceleration of the cat?

We know that according to the first equation of motion,

[tex]v-u=at[/tex]

Given to us

Time is taken by the cat to reach the final velocity = 2 seconds

Final velocity of the cat = 10 m/s

The initial velocity of the cat = 0 m*/s

Substitute the values in the equation,

[tex]v-u=at\\\\10-0 = a(2)\\\\a = 5\ m/s^2[/tex]

Hence, the acceleration of the cat to reach its maximum velocity of 10 m/s in 2 seconds is 5m/s².
