    Hi all

    How are you ...

    I want the ideas or for solving those questions .

    1 ) The piston of steam engine moves with simple Harmonic motion .
    The crank rotates at 150 rpm and the stroke length is 2 m . Find the velocity and acceleration of the piston when it is at a distance of 0.8 m from the center .

    2 ) A body moving with simple harmonic motion has an amplitude of 1 meter and the time for one complete oscillation is 2 seconds . Determine the velocity and acceleration of the body after 0.4 second from the mean position ?

    I want the ideas for solving those questions and please tell what the considerations take on solve like those questions
