A cowboy stands on horizontal ground between two parallel vertical cliffs. He is not midway between the cliffs. He fires a shot and hears its echoes. The second echo arrives 1.84 s after the first and 1.63 s before the third. Consider only the sound traveling parallel to the ground and reflecting from the cliffs. (Take the speed of sound as 343 m/s.)
(a) What is the distance between the cliffs? m
(b) If he can hear a fourth echo, how long after the third echo does it arrive? s
A stone is thrown horizontally at a speed of 4.9 m/s from the top of a cliff 89.5 m high, how long does it take the stone to reach the bottom of the cliff.
A continuous line of charge lies along an x axis, extending from x = +x0 to positive infinity. The line carries charge with the uniform linear charge density λ0. What are the magnitude and direction of the electric field at the origin.
