Question

A cow is walking at a velocity of 1 m/s and speeds up to 8 m/s in 7 seconds. Calculate the acceleration of the cow. Round your answer to 2 decimal places

Answer 1

`a=1\ m/s^2`

Step-by-step explanation:

Given that,

Initial velocity, u = 1 m/s

Final velocity, v = 8 m/s

Time, t = 7 s

We need to find the acceleration of the cow. Let it is a. It is equal to the rate of change of velocity. Its formula is :

`a=(v-u)/(t)\\\\a=(8-1)/(7)\\\\a=1\ m/s^2`

So, the acceleration of the cow is
`1\ m/s^2`.
