tw e-Probems Question 1 Flying Circus of Physics A roller-coaster car has a mass of 1030 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 24 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction) FN on the car from the track if the car's speed is v = 9.5 m/s? (b) What is Fy if v -17 m/s? Use g-9.81 m/s2 (a) Numbar Units (b) Number eview Scare Review Results by Study Question Attemts: of 12 sed FOR LATER SUSHIT ANSWER

Explanation / Answer

here,

mass , m = 1030 kg

radius , r = 24 m

a)

v = 9.5 m/s

at the top of hill

the normal force , Fn = m * v^2 /r - m * g

Fn = 1030 * ( 9.5^2 /24 - 9.81) N

Fn = - 6231.1 N

the normal force at the top is- 6231.1 N

b)

v = 17 m/s

at the top of hill

the normal force , Fn = m * v^2 /r - m * g

Fn = 1030 * ( 17^2 /24 - 9.81) N

Fn = 2298.6 N

the normal force at the top is 2298.6 N
