A 6-column table with 2 rows. The first column labeled number of washers has entries 1, 2. The second column labeled initial velocity v subscript 1 (meters per second) has entries 0.11, 0.13. The third column labeled final velocity v subscript 2 (meters per second) has entries 0.28, 0.36. The fourth column labeled time to travel 0.25 meters t subscript 1 (seconds) has entries 2.23, 1.96. The fifth column labeled time to travel 0.5 meters t subscript 2 (seconds) has entries 3.13, 2.61. The sixth column labeled Acceleration a = StartFraction (v subscript 2 minus v subscript 1) over (t subscript 2 minus t subscript 1) EndFraction (meters per second squared) has entries 0.19 and empty. The acceleration of the car with two washers added to the string would be

The equation that describes a transverse wave on a string is y = (0.0120 m)sin[(927 rad/s)t - (3.00 rad/m)x] where y is the displacement of a string particle and x is the position of the particle on the string. the wave is traveling in the +x direction. what is the speed v of the wave?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
