If a force of 10 N is applied to a 4.5 kg object, then the object will accelerate at 2.22 m/s2? True or false
a = F/m = 2.22222... m/s^2
That rounds off to 2.2, with two significant figures. They should not present three sig. figs. as the only true/false choice.
They probably want you to say "true"

true
To find out if the statement is true or false, we need to use the formula for Newton's second law of motion:
Force (F) = mass (m) × acceleration (a)
Rearranging the formula, we can solve for acceleration:
a = F / m
In this case, we have a force (F) of 10 N and a mass (m) of 4.5 kg. Let's substitute these values into the formula:
a = 10 N / 4.5 kg
Calculating this, we get:
a ≈ 2.222 m/s²
So, the correct value for the acceleration is approximately 2.222 m/s².
Comparing this to the given statement, we can see that the object will accelerate at approximately 2.22 m/s2. Therefore, the statement is true.
