Question

A force of 5 N accelerates an object. The object’s mass is 50 g. What is the acceleration of the object? (Formula: F=ma)

0.01 m/s2
0.1 m/s2
10 m/s2
100 m/s2

Answer 1

To find the acceleration of the object, we can use Newton's second law of motion, which states:

\[ F = ma \]

Where:
- \( F \) is the force applied (in Newtons)
- \( m \) is the mass of the object (in kilograms)
- \( a \) is the acceleration (in meters per second squared)

First, we need to convert the mass from grams to kilograms:

\[
50 \, \text{g} = 50 \, \text{g} \times \frac{1 \, \text{kg}}{1000 \, \text{g}} = 0.05 \, \text{kg}
\]

Now, we can rearrange the formula to solve for acceleration \( a \):

\[
a = \frac{F}{m}
\]

Substituting in the values:

\[
a = \frac{5 \, \text{N}}{0.05 \, \text{kg}} = 100 \, \text{m/s}^2
\]

Thus, the acceleration of the object is \( 100 \, \text{m/s}^2 \).

The correct answer is **100 m/s²**.
