Two radio antennas a and b radiate in phase. antenna b is a distance of 140 m to the right of antenna a . consider point q along the extension of the line connecting the antennas, a horizontal distance of 30.0 m to the right of antenna b. the frequency, and hence the wavelength, of the emitted waves can be varied.
a)what is the longest wavelength for which there will be destructive interference at point ?
b)what is the longest wavelength for which there will be constructive interference at point ?

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
