Question

What acceleration is produced when a 15 kg body is acted on by a horizontal force of 30 N?

a)2 m/s²
b)1 m/s²
c)0.5 m/s²
d)3 m/s²

Answer 1

The acceleration produced by a 30 N force on a 15 kg body is 2 m/s², obtained by using the equation F = m × a and solving for a which equals F / m.

Step-by-step explanation:

The question asks about the acceleration produced when a 15 kg body is acted on by a horizontal force of 30 N. To calculate the acceleration, we use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Calculation:

To find the acceleration (a), we use the equation:
F = m × a
Where:
F = force (in newtons, N)
m = mass (in kilograms, kg)
a = acceleration (in meters per second squared, m/s²)

So, a = F / m
a = 30 N / 15 kg
a = 2 m/s²

Therefore, the correct answer is 2 m/s², and the option is (a).
