The velocity v of a particle executing simple harmonic motion is given by the equation v = 50 (5 t) cm/s . The amplitude and time period of the motion are, respectively
Options
- A50 cm , 0.4 s
- B10 cm , 2.5 s
- C10 cm , 0.4 s
- D50 cm , 2.5 s
Correct answer
C. 10 cm , 0.4 s
Step-by-step solution
The standard equation for the velocity of a particle in simple harmonic motion is: v = A ( t) Given equation: v = 50 (5 t) cm/s Comparing the given equation with the standard equation, we get: = 5 rad/s A = 50 cm/s The time period T is: T = 2 = 2 5 = 0.4 s The amplitude A is: A = 50 = 50 5 = 10 cm Thus, the amplitude is 10 cm and the time period is 0.4 s . Answer: 10 cm , 0.4 s
