Consider a string of length 1.0 meter, fixed at both ends, with mass 100 grams and tension 100 Newtons. Give the number of nodes and antinodes set up on the string if it is driven at a frequency of 95 hertz. Be sure to include the ends of the string in your count. (7,6). Required:
Construct a wave in the applet that has four antinodes. Give the value of the expression T/muf^2 where is the tension, is the linear density, and is the driving frequency.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
