The "Screaming Swing" is a carnival ride that is-not surprisingly-a giant swing. It's actually two swings moving in opposite directions. At the bottom of its arc, riders are moving at 30 m/s with respect to the ground in a 44 m-diameter circle.

Question

At the bottom of the ride, as they pass each other, how fast do the riders move with respect to each other?

I've figured out that the acceleration is 41 m/s^2 and this equates to 4.2g's. Please help me with this last part!

Answer 1

30m/s+30m/s=60m/s
