#"4.5 m/s"^2#

From Newton’s second law

#"F = ma"#

where

F = Force

m = mass

a = acceleration

#"Acceleration" = "F"/"m" = "72 N"/"16 kg" = "4.5 m/s"^2#

#4.5 \ "m/s"^2#

We use Newton's second law, which states that,

#F=ma#

#m# is the mass of the object in kilograms

#a# is the acceleration in meters per second

And so,

#72 \ "N"=16 \ "kg"*a#

#a=(72 \ "N")/(16 \ "kg")#

#=4.5 \ "m/s"^2#
