Una máquina de mezclar concreto tiene un cilindro hueco de radio 1,5 m. El fabricante especifica que su rapidez se puede incrementar en 1,0 m/s cada segundo. Determine la aceleración total de una piedra en la base del cilindro vertical si en un instante determinado su rapidez es de 2,0 m/s. Asuma que el cilindro gira en sentido horario y que la piedra está en contacto con la pared del cilindro.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
