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

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 :

So, the acceleration of the cow is .

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
