Two loudspeakers are 2.0 m apart and in phase with each other. Both emit 700 Hz sound waves into a room where the speed of sound is 342 m/s. A listener stands 5.0 m in front of the loudspeakers and 2.0 m to one side of the center as shown in Figure Q2. i. Is the interference at this point constructive, destructive or something in between? Explain.
ii. How will the situation differ if the loudspeakers are out of phase?

Aspacecraft that renters the earth’s atmosphere drastically slows down. the amount of kinetic energy the spacecraft has as it reenters the earths atmosphere

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
