Question

Rose got out of bed and walked from her room to the bathroom 10 m/s in 2s. She was traveling southeast. What was her acceleration?

Answer 1

Acceleration = 5m/s² Southeast

Step-by-step explanation:

Given the following data;

Final velocity = 10 m/s

Time = 2secs

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

`Acceleration (a) = (final \; velocity - initial \; velocity)/(time)`

`a = (v - u)/(t)`

Where,

a is acceleration measured in
`ms^(-2)`

v and u is final and initial velocity respectively, measured in
`ms^(-1)`

t is time measured in seconds.

We know that Initial velocity = 0m/s

Substituting into the equation, we have;

`a = (10 - 0)/(2)`

`a = (10)/(2)`

Acceleration = 5m/s² Southeast.
