A 440 kg roller coaster car is going 26 m/s when it reaches the lowest point on the track. If the car started from rest at the top of a hill, how much higher was that point on the track than the lowest point? (Use g = 9.80 m/s2, and ignore friction.)

Respuesta :

Answer:

34.49 m

Step-by-step explanation:

Use the formula height = [tex]\frac{v^{2} }{2g}[/tex]

1. Substitute in the values given

26² / 2(9.8)

2. Simplify and solve

676 / 19.6 = 34.49
