What is the velocity of the boat when it reaches the buoy : A speedboat moving at 35.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of -3.5 m/s2 by reducing the throttle. How long does it take the boat to reach the buoy?

A particle leaves the origin with a speed : A particle leaves the origin with a speed of 3.3 times 10^6 m/s at 38 degrees to the positive x axis. It moves in a uniform electric field directed along positive y axis. Find Ey such that the particle will cross the x axis at x = 1.5 cm if the parti..

Compute the maximum transverse acceleration of the string : A string with both ends held fixed is vibrating in its third harmonic. The waves have a speed of 193m/s and a frequency of 240Hz. The amplitude of the standing wave at an antinodes is 0.440cm .

Ultrasound-frequencies above the human range of hearing : Ultrasound is the name given to frequencies above the human range of hearing, which is about 20000 Hz. Waves above this frequency, can be used to penetrate the body and to produce images with reflecting from surfaces.
