A speaker fixed to a moving platform moves toward a wall, emitting a steady sound with a frequency of 235 Hz . A person on the platform right next to the speaker detects the sound waves reflected off the wall and those emitted by the speaker. How fast should the platform move for the person to detect a beat frequency of 6.00 Hz ?
Take the speed of sound to be 344 m/s .

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
