Question

Which object would have the slowest speed at terminal velocity?(1 point) a. a 50-kilogram block with no parachute b. a 10-kilogram block with no parachute c. a 50-kilogram block with a large parachute d. a 10-kilogram block with a small parachute Skip to navigation

Answer 1

c. a 50-kilogram block with a large parachute.

Reason: Terminal velocity satisfies mg = ½ρC_dA v_t^2, so v_t = sqrt(2mg/(ρC_dA)). A large parachute greatly increases A (and C_d), reducing v_t enough that the 50-kg block with a large parachute falls slower than the others.
