Asmall, spring-loaded cannon launches a tennis ball from level ground with an initial speed vi at an angle θi with the horizontal. the tennis ball lands a horizontal distance r from its launch point. the highest point the tennis ball reaches during its flight is a distance r 12 above the ground. in terms of r and g, find the following. (you may ignore air ) the time interval during which the tennis ball is in motion(b) the tennis ball's speed at the peak of its path(c) the initial vertical component of its velocity

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.
