The problem asks us to find the acceleration of an object when a force is applied. We are given:
- Mass (m) = 20 kg
- Force (F) = 15 N
We use Newton’s Second Law:
Force = mass × acceleration
or
F = m × a
To find acceleration (a), we rearrange the formula:
a = F ÷ m
Now plug in the numbers:
a = 15 N ÷ 20 kg
a = 0.75 m/s²
Let’s double-check:
If you push a 20 kg object with 15 newtons of force, it should accelerate at less than 1 m/s² — and 0.75 makes sense because 15 is less than half of 20? Wait — actually, 15 is 3/4 of 20? No — 15 divided by 20 is 0.75. Yes, that’s correct.
So the acceleration is
0.75 meters per second squared.
Final Answer:
0.75 m/s²
