In an amusement park water slide, people slide down an essentially frictionless tube. the drop 3.0m and exit the slide, moving horizontally, 1.2m above a swimming pool. what horizontal distance do they travel from the exit point before hitting the water? does the mass of the person make any difference ?

please show work to explain!

3.8 m

No mass does not matter

Explanation:

It is given that the tube is frictionless which means there will be no loss of energy. To solve this question we can use the law of conservation of energy which states that energy cannot be created not destroyed but it can be converted from one form to another but energy remains conserved. The form of energies that exist in this system are Kinetic energy (KE) and potential energy (PE).

KE = ½ mv²

PE = mgh

another equation required in this question is equation of motion

s = ut + 1/2at²

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

correct it is c.) b b
