(a) In Example 5.18 (Section 5.3), what value of D is required to make vt = 42 m/s for the skydiver? (b) If the skydiver’s daughter, whose mass is 45 kg, is falling through the air and has the same D (0.25 kg/m) as her father, what is the daughter’s terminal speed?

Solution 41E Step 1 of 4: (a) In Example 5.18 (Section 5.3), what value of D is required to make vt = 42 m/s for the skydiver Given that, Mass of the skydriver, m= 50 kg Terminal velocity, v t 42 m/s 2 Acceleration due to gravity,g=9.8 m/s To find, D= When falling down(FBD),
