Given displacement of a particle executing SHM `y(t)=A cos (omegat+phi)`. Plot instantaneous displacement, velocity and acceleration of particle with respect to time.

Explanation

`y(t)=A cos (omegat+phi)`
`v(t)=-omega A sin (omega t+phi)`
and `a(t)=-omega^(2)A cos (omegat +phi)`
and note that `" "cos ((pi)/(2)+phi)=-sin phi" "sin((pi)/(2)+phi)=+cos phi`
`cos (pi+phi)=-cos phi" "sin(pi+phi)=-sin phi`
`cos((3pi)/(2)+phi)=+sin phi" "sin ((3pi)/(2)+phi)=-cos phi`
and `cos (2pi+phi)=+cos phi" "and sin (2pi+phi)=+sin phi`
