Question

Suppose a cheetah running at a velocity of 5 m/s east slows down. After 15 seconds, the cheetah has reached a velocity of 25 m/s. What is the
cheetah's acceleration?

Answer 1

Answer:

1.33m/s²

Explanation:

Given parameters:

Initial velocity  = 5m/s

Final velocity  = 25m/s

Time taken  = 15seconds

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of velocity with time.

  Acceleration  = $\frac{v - u}{t}$  

  v is the final velocity

  u is the initial velocity

  t is the time taken

 So;

    Acceleration  = $\frac{25 - 5}{15}$    = 1.33m/s²
