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

54m

Step-by-step 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 =
`((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 =
`(18 - 0)/(2)` x 6 = 54m
