F=m*a
F=65 kg *9.8 m/s^2
F=637 N (Newtons) — this is the weight
If you are designing a roller coaster that goes upside down, you may consider of course seat belts or something that goes around you to keep yourself safe.
The wavelength is 2m.
Hence, Option c) 2m is the correct answer
Given that;
Frequency; 
Speed; 
Wavelength; 
using the expression for the relations between wavelength, frequency and speed of wave:
Where 
is wavelength, f is frequency and v is speed.
We substitute our given values into the equation
The wavelength is 2m.
Hence, Option c) 2m is the correct answer.
