What is NOT a service fault in volleyball? Server bounces ball and then serves. . Server steps over the line O serve goes out of bounds

The force will determine the acceleration.

Which of the following is an example of units for speed

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
