Suppose a lion running at a velocity of 10 m/s east slows down. After 30 seconds, the lion has stopped. What is the
lion's acceleration?

Explanation:

Given that,

Initial velocity, u = 10 m/s

Final velocity, v = 0 (stops)

Time, t = 30 s

We need to find the acceleration of the lion.

We know that,

Acceleration = rate of change of velocity

So, the acceleration of the lion is .
