Answer:
The maximum velocity of a body of mass 200g performing in Simple Harmonic Motion (SHM) at a frequency of 50Hz at a distance of 100cm from the main position is 2000m/s. This can be calculated using the equation: velocity = (2π x frequency) x amplitude, where frequency is 50Hz, amplitude is 100cm, and 2π is equal to 6.28. Thus, the maximum velocity is (6.28 x 50) x 100 = 3140m/s.
