Math Problem Statement
Athena is tracking the motion of a proton undergoing uniform circular motion in a cyclotron. At time 𝑡1 = 3.25 ns she reported the electron to be at ⟨50.0 cm, 50.0 cm⟩ with velocity −(4.29 × 10^7 m/s)î and acceleration directed along the +𝑦-axis. Then at time 𝑡2 = 58.2 ns it had velocity −(4.29 × 10^7 m/s)î and acceleration along the −𝑥-axis. The time 𝑡2 − 𝑡1 is less than one period.
Evaluate this first then answer the following: A. What is the period of revolution of the electron? B. Where is the center of the circular path located? C. What is the centripetal acceleration of the electron?
