Un martillo arrojado verticalmente hacia arriba en direccion a la cumbre
de un techo de 16m de altura ¿Que velocidad
inicial minima se requirio para que
llegara ahi?

An object is moving east, and it’s velocity changes from 65m/s to 25m/s in 10 seconds. which describes the acceleration?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

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.
