Complete Question
The cars of a roller-coaster ride have a speed of 19.0 km/h as they pass over the top of the circular track. Neglect any friction and calculate their speed v when they reach the horizontal bottom position. At the top position, the radius of the circular path of their mass centers is 21 m, and all six cars have the same mass.V = -18 m What is v?X km/h

Explanation:
A lot of origami used symmetry of paper to create things. And it happens that a lot of things in science can be inferred or easily determined using symmetry. The most recent thing I can think of is exploiting symmetry in Gauss’s Law for electrical flux

Answer:
- 3/5" = 12'
- 1 3/4" = 35'
- 1 1/4" = 25'
- 9/10" = 18'
- 2 13/20" = 53'
Explanation:
One number is wrong; they all lack units.
The basic ratio is 1" = 20', so you can divide feet by 20 to find inches.
- 3/5" = 12'
- 1 3/4" = 35'
- 1 1/4" = 25'
- 9/10" = 18'
- 2 13/20" = 53'
Perhaps you want decimal inches:
- 0.60" = 12'
- 1.75" = 35'
- 1.25" = 25'
- 0.90" = 18'
- 2.65" = 53'
