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

• Physical Science -

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"
