The correct Answer is:
To find the displacement of a particle after 10 seconds starting from rest with a uniform acceleration of \(2 \, \text{m/s}^2\), we will use the first equation of motion:
\[
S = ut + \frac{1}{2} a t^2
\]
### Step-by-Step Solution:
1. **Identify the given values:**
- Initial velocity (\(u\)) = 0 (since the particle starts from rest)
- Time taken (\(t\)) = 10 seconds
- Acceleration (\(a\)) = \(2 \, \text{m/s}^2\)
2. **Substitute the values into the equation:**
\[
S = ut + \frac{1}{2} a t^2
\]
Substituting the known values:
\[
S = (0)(10) + \frac{1}{2} (2) (10^2)
\]
3. **Calculate the first term:**
\[
(0)(10) = 0
\]
4. **Calculate the second term:**
\[
\frac{1}{2} (2) (10^2) = \frac{1}{2} (2) (100) = 1 \times 100 = 100
\]
5. **Combine the results:**
\[
S = 0 + 100 = 100 \, \text{meters}
\]
### Final Result:
The displacement of the particle after 10 seconds is \(100 \, \text{meters}\).
