# Acceleration Question!? watch

1. Here's a simple question but im not sure if the answer i got is right which was 29.9.

An object of mass 3.2kg is acted on by two forces which are at right angles to each other. The resultant force is 11.5N

Calculate the acceleration of the object

From John Wood
2. Did you calculate the resultant force yourself using pythagoras' theorem or was it given?

Then you just use F=ma, where F is the resultant force.
3. what?

a = F/m = 11.5/3.2 = 3.6 m s^-2
is there something I'm missing?
4. what?

a = F/m = 11.5/3.2 = 3.6 m s^-2
is there something I'm missing?
You're right. Whats the problem? Thats what Maya said!
