an 8-newton foce is applied to a 4-kg object. what is the rate of acceleration. a.4 meters per second
b.8 meters per second
c.2 meters per second
d.12 meters per second
a = F/m = 8/4 = 2
To find the rate of acceleration, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a). We can rearrange the equation to solve for acceleration (a = F / m).
In this case, the force applied is 8 Newtons and the mass of the object is 4 kg. Plugging these values into the equation, we get:
a = 8 N / 4 kg = 2 meters per second
Therefore, the rate of acceleration is 2 meters per second. Hence, the correct answer is option c.
