Final answer:
The force acting on the body is calculated by the Newton's Second Law (F=ma). Here, the acceleration is calculated by subtracting the initial velocity from the final velocity. The force is then found by multiplying the mass (1kg) by the acceleration (10m/s^2), providing a resultant force of 10 Newtons.
Step-by-step explanation:
The subject matter for the question pertains to Newton's Second Law of Motion, which states that Force equals mass times acceleration (F=ma). In this scenario, you are given the initial and final velocity, but not the time. Therefore, we need to assume that the time interval is one second for the purpose of this calculation. Acceleration is the rate of change of velocity. Given the initial velocity is 15m/s and the final velocity is 25m/s, the acceleration would be final velocity - initial velocity or 10m/s2.
Next, calculate the force using Newton's Second Law (F = ma). So the force is mass times acceleration, which is 1kg times 10m/s2, and so the force acting on the body is 10 Newtons.
