A force of 63N acting upon a given object results in an acceleration of 9 m/s^2. If the magnitude of the force acting upon the same object is changed to 28 N, what will the object's acceleration become?

#"4 m/s"^2#

Use Newton's #2^(nd)# Law:

#F= ma #

Since the mass of the object doesn't change,

#m = F/a = F_1/a_1 = F_2/a_2#

then solve for #a_2#:

#a_2= F_2/F_1*a_1#

#a_2= "28 N"/"63 N" * "9 m/s"^2 = "4 m/s"^2#

Note: Less force implies less acceleration; the answer is consistent. Checked.
