A particle with a mass of 2.3 * 10-20 kg is oscillating with simple harmonic motion with a period of 3.0 * 10-5 s and a maximum speed of 2.2 * 103 m/s. Calculate (a) the angular frequency and (b) the maximum displacement of the particle.

angular frequency is 209439.51 rad/sec

maximum displacement is 0.010504 m

Explanation:

Given data

mass = 2.3 * 10^-20 kg

period = 3.0 * 10^-5 s

maximum speed = 2.2 * 10^3 m/s

to find out

the angular frequency and maximum displacement

solution

we know angular frequency formula that is

angular frequency = 2 π / period

put here period value we get angular frequency

angular frequency = 2 π / 3.0 * 10^-5

angular frequency is 209439.51 rad/sec

maximum displacement formula is

speed = angular frequency * maximum displacement

put all value and we get maximum displacement

maximum displacement = 2.2 * 10^3 / 209439.51

maximum displacement is 0.010504 m
