A student has a cup containing coffee. He observes the color of the coffee. He weighs the cup containing coffee. He then adds 25 g of sugar to the coffee. The table shows the student's results.
TABLE
Substance Weight (g) Color Coffee and cup 335 Dark brown
25 White Sugar
Coffee and cup after sugar is added 360 Dark brown
The student concludes that the sugar added to the coffee still exists.
What evidence best supports this conclusion?
A. The sugar welghs 25 g.
B. The color of the sugar is white.
C. The coffee and cup after the sugar is added is 360 g.
D. The color of the coffee after the sugar is added Is dark brown.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
