Two people start at the same place and walk around a circular lake in opposite directions. one has an angular speed of 1.11 x 10-3 rad/s, while the other has an angular speed of 8.40 x 10-3 rad/s. how long will it be before they meet

Respuesta :

The time taken before the two people will meet is 11 minutes.

Time taken before they meet

The time taken before the two people will meet is calculated from the principle of relative velocity.

(ω₁ + ω₂)t = θ

where:

  • ω₁ is angular speed of the first person
  • ω₂ is the angular speed of the second person
  • t is time of motion
  • θ is angular displacement

(1.11 x 10⁻³  + 8.4 x 10⁻³)t = 2π

(9.51 x 10⁻³)t = 2π

t = 2π/9.51 x 10⁻³

t = 660.7 secs

t = 11 mins

Thus, the time taken before the two people will meet is 11 minutes.
