A ball has a mass of 140 g. What is the force needed to accelerate the ball at [tex]$25 \, \text{m/s}^2$[/tex]?

(Formula: [tex]$F = ma$[/tex])

A. 3.5 N
B. 115 N
C. 165 N
D. 4.5 N

Answer :

Sure! Let's solve the problem step-by-step.

1. Identify the given values.
- Mass of the ball: 140 grams
- Acceleration: [tex]\(25 \, \text{m/s}^2\)[/tex]

2. Convert mass to kilograms.
- Since force is calculated in the SI unit of newtons, and one newton is defined as [tex]\(1 \, \text{kg} \cdot \text{m/s}^2\)[/tex], we need to convert the mass from grams to kilograms.
- To convert grams to kilograms, divide by 1000:
[tex]\[
\text{Mass in kg} = \frac{140 \, \text{g}}{1000} = 0.14 \, \text{kg}
\][/tex]

3. Apply the formula for force.
- The formula to calculate force is given by:
[tex]\[
F = m \times a
\][/tex]
- Where:
- [tex]\(F\)[/tex] is the force in newtons (N),
- [tex]\(m\)[/tex] is the mass in kilograms (kg),
- [tex]\(a\)[/tex] is the acceleration in meters per second squared ([tex]\(\text{m/s}^2\)[/tex]).

4. Substitute the values into the formula.
- Using the mass [tex]\(0.14 \, \text{kg}\)[/tex] and the acceleration [tex]\(25 \, \text{m/s}^2\)[/tex]:
[tex]\[
F = 0.14 \, \text{kg} \times 25 \, \text{m/s}^2
\][/tex]

5. Calculate the force.
- Multiplying these gives:
[tex]\[
F = 3.5 \, \text{N}
\][/tex]

So, the force needed to accelerate the ball at [tex]\(25 \, \text{m/s}^2\)[/tex] is [tex]\(3.5 \, \text{N}\)[/tex].
