If a 30N force is applied to a stationary object of mass 10kg, at what speed will the object accelerate?
By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms-2 so hence, the object will accelerate at 3ms-2.
