In an amusement park water slide, people slide down an essentially frictionless tube. They drop 3.2m and exit the slide, moving horizontally, 1.4m above a swimming pool.
a) What horizontal distance do they travel from the exit point before hitting the water?
b) Does the mass of the person make any difference?
