A constant force acting on a body of mass of 5 kg change its speed fro...
Here,m = 5kg, M = 5ms-1, v- 10ms-1, t = 10s, Using v = u + at
As F = ma
∴ F = (5kg)(0.5ms−2) = 2.5N
As F = ma
∴ F = (5kg)(0.5ms−2) = 2.5N

Understanding the Problem
To find the force acting on a body, we will use Newton's second law of motion and the concept of acceleration.
Given Data:
- Mass (m) = 5 kg
- Initial speed (u) = 5 m/s
- Final speed (v) = 10 m/s
- Time (t) = 10 s
Step 1: Calculate Acceleration
Acceleration (a) can be calculated using the formula:
a = (v - u) / t
Substituting the values:
a = (10 m/s - 5 m/s) / 10 s
a = 5 m/s / 10 s
a = 0.5 m/s²
Step 2: Apply Newton's Second Law
Newton's second law states:
F = m * a
Where:
F = Force
m = Mass
a = Acceleration
Substituting the known values:
F = 5 kg * 0.5 m/s²
F = 2.5 N
Conclusion
The force acting on the body is 2.5 N, which corresponds to option 'C'.
Summary of the Calculation:
- Initial speed = 5 m/s
- Final speed = 10 m/s
- Time taken = 10 s
- Acceleration = 0.5 m/s²
- Force = 2.5 N
This detailed breakdown confirms that option 'C' is indeed the correct answer.
