Physics: Calculating Final Velocity
To find the final velocity of the body, we can use the equations of motion. The problem provides the mass of the body, the acceleration produced by a force, and the time elapsed.
Given Information:
- Mass of the body, \(m = 4\) kg
- Initial velocity, \(u = 0\) m/s (since the body is at rest)
- Acceleration, \(a = 3\) m/s²
- Time, \(t = 5\) s
Applying the Equation of Motion:
The first equation of motion relates final velocity (\(v\)), initial velocity (\(u\)), acceleration (\(a\)), and time (\(t\)):
\( v = u + at \)
Calculation:
Substitute the given values into the equation:
\( v = 0 \, \text{m/s} + (3 \, \text{m/s}^2) \times (5 \, \text{s}) \)
\( v = 0 + 15 \, \text{m/s} \)
\( v = 15 \, \text{m/s} \)
Result:
The final velocity of the body after 5 seconds is 15 m/s.
