Aphysics student of mass 54 kg rides a ferris wheel around in a vertical circle of radius 12 m at a constant speed of 7.1 m/s. what is the difference between the magnitude of the normal force on her from the seat when she goes through the lowest point of the circular path compared to the force on her going through the highest point?

Answer

given,

mass of the student = 54 kg

radius of the vertical circle = 12 m

constant speed of the wheel = 7.1 m/s

normal force at height point = ?

normal force at lowest point = ?

F_{normal}(at highest point)

           =

           =

           =

           = 302.35 N

F_{normal}(at lowest point)

           =

           =

           =

           = 756.05 N

the answer is 3.1 his answer is wrong mines is right

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
