35. If you know that a 1-kg object weighs 10 N, confirm that the acceleration of a 1-kg stone in free fall is 10 m/s².

36. A simple rearrangement of Newton’s second law gives
. Show that a net force of 84 N is needed to give a 12-kg package an acceleration of 7.0 m/s². (Note: The units kg.m/s²
and N are equivalent.)
