Determine the drag coefficient ca needed for a parachutist of mass m = 68.1 kg to have a velocity of 40 m/s after free-falling for time t = 10 s. Assume the acceleration due to gravity is 9.8 m/s². gm v(t) m - e Cd A. Isolate the Cd and Simplify the equation. B. Derive or solve the derivative of cd

Explain the meaning of position, displacement, and distance traveled as they apply to an object moving along a line. Select the correct answer below. O A. The position of an object moving along a line is the location of the object relative to the origin. The displacement is the change from initial position to time t= a. The distance traveled between t= a and t=b is v(t) dt, where v(t) is the velocity at time t. a O B. The position of an object moving along a line is the location of the object relative to the origin. The displacement is the change in position between time t= a and t= b. The distance traveled betweent=a and b t=b is | v(t) dt, where v(t) is the velocity at time t. O C. The position of an object moving along a line is the location of the object relative to the origin. The distance traveled between t= a and t= b is v(t) dt, where v(t) is the velocity at time t. The displacement is the change a in distance between timet=a and t= b. O D. The position of an object moving…
