A falling body on Earth will generally not fall at constant acceleration in reality, due to air resistance (or drag). The equation for the drag force Fd is Fd = 0.5 (Cd A) ρ v2 where Cd is the unitless drag coefficient of a body, A is its cross-sectional area, ρ is the density of the air, and v is the body's velocity with respect to the atmosphere.(b) Look up and then see if you can also calculate the terminal...

A particle leaves the origin with an initial velocity v⃗ =(2.40m/s)x^, and moves with constant acceleration a⃗ =(−1.90m/s2)x^+(3.20m/s2)y^. How far does the particle move in the x direction before turning around? What is the particle's velocity at this time? Calculate the particle's position at t = 0.500 s, 1.00 s, 1.50 s, and 2.00 s. Use these results to sketch x and y positions versus time for the particle.
