A roller-coaster car has a mass of 1120 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 16 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 = 7.8 m/s? (b) What is FN if v = 16 m/s? Use g=9.81 m/s2.

Step 1

This can be calculated using the formula: F_gravity = m * g where m is the mass of the roller-coaster car (1120 kg) and g is the acceleration due to gravity (9.81 m/s²). F_gravity = 1120 kg * 9.81 m/s² Now, we need to find the centripetal force acting on the Show more…
