Assume that two thirds of Earths surface is coveredwith water to an average depth of 3 km. Calculate howmany nuclei of deuterium exist (2H is 0.015% abundant).Estimate using reaction (13.22) how much energyis available through fusion.

TwoDimensional Kinematics Motion in Two Dimensions ● Motion in the xdimension and ydimension do not depend on each other; they are independent. ● Assumptions for projectile motion: ○ Air resistance 2 ○ g=9.81m/s ○ Earth’s rotation ● If something is thrown at an upward angle, x is a constant and y will be affected by gravity FILL THIS IN ● Position as a function of time ● Velocity as a function of position ● Velocity as a function of time Zero Launch Angle ● Launch angle is the direction of initial velocity with respect to horizontal. Velocity in x direction: 2m/s Height of table: 0.6m ● Position as a function of time ● 0 = 0.6m ½ (9.81) t ○ t=0.35s ● x =0 + (2m/s)(0.35s) ○ x = 0.7m General Launch Angle ● When you have a general launch angle, you must break down the angle into x and y components
