A 0.057 kg tennis ball and a tennis racket collide. The racket has an initial momentum of -2.80 kg-m/s and a final momentum of -1.97 kg-m/s. The ball
has an initial momentum of 0.02565 kg-m/s. If you assume the collision is
elastic, what is the final velocity of the ball?
A. -83.26 m/s
B. -4.75 m/s
O c.-14.11 m/s
OD. -0.80 m/s

Aball is thrown horizontally from a cliff at 8m/s .in what direction is the ball moving 2s later?

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
