    Circular motion and parabolic orbit

    Homework Statement A point object of mass m is connected to an inertialess string of length L, the other end of which is connected to a fixed point O. At time t=0, the object is assumed to move horizontally in a vertical plane from the bottom point A (OA=L). in the clockwise direction with...

    Ball thrown vertically upward with initial speed 20 m/s

    The required equation is: 4.9t2 - 20t + 15 = 0 because h = ut - 1/2gt2 since the ball is launched vertically upward g become negative

    Piston pressure after rotating cylinder 180 degrees

    so, P1 = p + Mg/S ... (1) P2 + Mg/S = p or, P1 + 2Mg/S = 2p ... (2) (since, P2 = P1/2) subtracting (1) from (2) 2Mg/s = p - Mg/s or, p = 3Mg/s So, the correct answer is option (a). Thanks for your help.

    Piston pressure after rotating cylinder 180 degrees

    Homework Statement A cylinder with a frictionless piston of mass M and cross section S is placed vertically in an atmosphere of pressure p. The cylinder is rotated 180 degree so that the opening of the cylinder faces down. During the operation the temperature of the gas inside the cylinder is...
