It means retardation on body is of 2m/s^2. so retardation force must be equal to 4N. so if one want the body to keep moving one would have to overcome this retarding force acting on the body which can be provided by applying external force of 4N on the body which should be acting opposite to the retarding force. so ans is 4N

Calculating the Force Required to Keep the Body Moving
• Given parameters:
- Mass of the body (m) = 2 kg
- Initial velocity (u) = 4 m/s
- Time taken to come to rest (t) = 2 seconds
- Final velocity (v) = 0 m/s
- Required velocity (v') = 4 m/s
• Using the equation of motion: v = u + at
- Substituting the values: 0 = 4 + a * 2
- Solving for acceleration (a): a = -2 m/s²
• Now, we know that force (F) is related to acceleration (a) and mass (m) through Newton's second law: F = ma
• To calculate the force required to keep the body moving at 4 m/s:
- F = 2 kg * (-2 m/s²)
- F = -4 N
• Therefore, the force required to keep the body moving on the same surface with a velocity of 4 m/s is 4 Newtons in the opposite direction of motion.
By applying the concepts of Newton's laws of motion and equations of motion, we can determine the force required to maintain the motion of a body on a horizontal surface.
