2.A 30 g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?
Added by Anthony C.
Step 1
Step 1: Identify the given values in the problem: - Mass of the car, \( m = 30 \) g - Height of the hill, \( h = 12 \) cm - Velocity of the car, \( v = 154 \) cm/s - Length of the horizontal track, \( d = 275 \) cm Show more…

A roller-coaster car has a mass of 1300 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 20 m, its speed is not changing. At the top of the hill, what are the (a) magnitude FN and (b) direction (up or down) of the normal force on the car from the track if the car’s speed is v 11 m/s? What are (c) FN and (d) the direction if v 14 m/s?
