#17. a filled treasure chest of mass 375 kg with a long rope tied around its center lies in the middle of a room. dirk wishes to drag the chest, but there is a coefficient of static friction of = 0.52. if the angle between the rope and the floor is 30o, what is the magnitude of the tension required to just get the chest moving?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
