The drawing shows a loudspeaker A and point C, where a listeer is positioned. A second loudspeaker B is located somewhere to the right of A. Both speakers vibrate in phase and are playing a 51.5-Hz tone. The speed of sound is 344 m/s. What is the closest to speak A that speaker B can be located, so that the listener hears no sound?

Wanted to check a practice probem, thanks!

A 9,700-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. Compute how much kinetic energy was "lost" in this inelastic collision in J.

a)Find an expression for the bullet's initial speed v_B in terms of m, M, k, and d. Express your answer in terms of the variables m M k d b)What was the speed of a 1.8 g bullet if the block's mass is 1.1 kg and if the spring, with k = 37 N/m , was compressed by 16 cm? Express your answer in meters per second. c)What percentage of the bullet's energy is "lost"? Express your answer in percent to four significant figures.

a) how much net work is required to accelerate a 1135-kg car from 18 m/s to 40 m/s? b) how much net work is required to accelerate a 955-kg car from 17 m/s to 45 m/s? c) how much net work is required to accelerate a 1089-kg car from 16 m/s to 36 m/s?
