Movies and tv shows sometimes portray a person being thrown backwards a sizable distance as a result of being struck by a bullet. calculate the maximum distance that a 70.0-kg object would fly backwards if it is struck by a 10.0-gram projectile moving with a velocity 355 m/s which then completely embeds itself in the object. assume that the angle of this perfectly inelastic collision is such that the combined mass is launched at an angle of 45 degrees above the horizontal, and neglect the effects of air resistance. based on this calculation, evaluate the realism (or lack thereof) of the tv/movie portrayal.

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s. part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
