A2.00 m long string has a mass of (a+1.50) g. a (b+25.0) g mass is attached to the string and hung over a pulley (see illustration from one of the team problems). the end of the string is then vibrated at a frequency of (125+c) hz. find the wavelength for the wave generated. give your answer in centimeters (cm) and with 3 significant figures.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.
