One of the ever-popular favourites in the playground is the child swing. Kids love to ride the swings at the playground. Given the following situation: Ann (20kg) and Tom (30kg argue in front of two child swings (Length 2.4m and 2.5m), who is able to swing faster. Ann worries about her less weight and wants to take the longer swing. Tom agrees assuming that his much greater weight will easily outplay the difference of 10cm according to the length of the two swings.
What is your advice for Tom?
