Question

A cat is moving at 18 m/s when it accelerates at 4 m/s2 for 2 seconds. What is his

Answer 1

Answer:

26m/s

Explanation:

Given parameters:

Initial velocity  = 18m/s

Time  = 2s

Acceleration  = 4m/s²

Unknown:

Final velocity

Solution:

To solve this problem, we use the expression below:

     Acceleration  = $\frac{v - u }{t}$

v is the final velocity

u is the initial velocity

 t is the time taken

    4   = $\frac{v - 18}{2}$    

      v - 18  = 8

       v  = 8 + 18 = 26m/s
