Find the moments of time when the particle is at the distance from the origin.
Find the moments of time when the particle is at the distance \( 10.0 \mathrm{cm} \) from the origin.
- A. \( 1.1,9, \) and \( 11 s \)
- B. \( 1,10, \) and \( 11 s \)
- C. \( 1.1,10, \) and \( 11 s \)
- D. \( 1.1,9, \) and \( 13 s \)
Step-by-step solution
The times correspond to solving |10t - t^2| = 10 (assuming x = 10t - t^2 cm), giving t ≈ 1.1 s (x=10), 9 s (x=10 on return), and 11 s (x=-10).
