Answer to Question #1614 in Mechanics | Relativity for aakriti goel
A particle executes SHM with a time period of 2 sec and amplitude 5cm find
(2) velocity (3) acceleration after 1/3 sec starting from mean position.
(i) displasement is x = 5 sin (2π/T t ) = 5 sin (π t ) [cm] x(t=1/3) = 5 sin (π/3) = 5*√3/2. (ii) then the velosity would be v = 5π cos (π t) [cm/s] v(t=1/3) =2.5π (iii) acceleration a = -5 π2 sin (π t) a(t=1/3)= -2.5π2√3
