Question

An object accelerates uniformly from rest. If the final velocity of the object after 6.0 s is
18 m/s east, how far did the object travel?

Answer 1

Answer:

54m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time taken  = 6s

Final velocity  = 18m/s east

Unknow:

How far did the object travel  = ?

Solution:

To solve this problem, we use one of the kinematics equation:

 We first find the acceleration which is the change in velocity

   

So;

        S  = $(\frac{v - u}{2} ) t$    

    S is the distance  

    v is the final velocity

    u is the initial velocity

    t is the time taken

  Therefore;

       S = $\frac{18 - 0}{2}$  x 6  = 54m
