Sagot :
Final answer:
The scenario involves a rider on a Ferris wheel with changing angular speed and acceleration, leading to a final calculation of the merry-go-round's angular speed.
Explanation:
The key concept here is the motion of a rider on a Ferris wheel with changing angular speed and acceleration.
- Angular Speed Increase: The rider is initially at rest on a 16m diameter Ferris wheel traveling at 10m/s, which slows to rest over two complete revolutions with decreasing angular acceleration.
- Calculation: To determine the angular speed of the Ferris wheel after the rider jumps on, we consider the mass of the child, initial speed, mass of the merry-go-round, and its radius.
- Analysis: By ignoring frictional torque, we can calculate the final angular speed of the merry-go-round using the given variables.
