Answer:

Introduction Purpose: Explore the interdependence of organisms by

performing an experiment with lima bean plants and earthworms. Question: How can the presence of one species benefit another in

the same ecosystem?

Hypothesis: If plants grow in soil containing worms, then the

plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.

A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?

sladkih [1.3K]

Answer:

$\boxed {\boxed {\sf A. \ 2 \ m/s^2}}$

Explanation:

Acceleration is the rate of velocity's change with time.

We can calculate it by dividing the change in velocity over time.

$a=\frac{v_f-v_i}{t}$

Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.

$v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s$

Substitute the values into the formula.

$a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }$

Solve the numerator first.

15 m/s - 5 m/s= 10 m/s

$a=\frac{10 \ m/s}{5 \ s}$

Divide.

$a= 2 \ m/s/s = 2 \ m/s^2$

The acceleration of the bus is <u>2 meters per second squared.</u>
