A 75kg passenger at the bottom of a roller coaster loop that has a radius of 20m. If the roller coaster car is moving 10m/s, what is the apparent weight of the passenger? g

The apparent weight of the passenger is 360 N

Explanation:

Given;

The mass of the passenger, m = 75 kg

radius of the loop, r = 20 m

velocity of the roller coaster, v = 10 m/s

Centripetal force acting on this passenger is given as;

where;

F is the centripetal force acting on the passenger

m is the mass of the passenger

v is the velocity of the passenger

r is the radius of the track

Real weight of the passenger,

W = mg

where;

g is acceleration due to gravity

W = 75 x 9.8

W = 735 N

Apparent weight of the passenger = Real weight - Centripetal force

Apparent weight of the passenger  = 735 N - 375 N

Apparent weight of the passenger = 360 N

Therefore, the apparent weight of the passenger is 360 N

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
