Final answer:
The acceleration of a 2.00 kg body pushed upward by a 25.0 N force is found using Newton's second law of motion and is calculated to be 12.5 m/s².
Step-by-step explanation:
To determine the acceleration of a body of mass 2.00 kg pushed upward by a 25.0 N vertical force, we can use Newton's second law of motion, which is stated as F = ma, where F is the force applied, m is the mass of the body, and a is the acceleration.
In this case, F = 25.0 N and m = 2.00 kg. Plugging these values into the equation, we get:
25.0 N = (2.00 kg)(a)
To find the acceleration, we divide both sides of the equation by the mass:
a = 25.0 N / 2.00 kg
a = 12.5 m/s²
Therefore, the acceleration of the body is 12.5 m/s², which corresponds to answer choice a).
