Question

23.A skydiver steps out velocity, the skydiver's: A. velocity decreases C. acceleration decreases. f a hot air balloon. While falling, but before D, acceleration increases. 24.The drag force on a skydiver+parachute of terminal velocity: A. is equal to 750N exactly C. is greater than 750 N combined weight mg 750N B. depends on whether the parachute is opes or so D. is less than 750 N. 25. Just after opening the parachute, the skydiver's: A. velocity is directed upwards C. acceleration is downwards, but reduced in magnitude B. acceleration is directed upwands D. velocity is zero for a brief insta END OF MULTIPLE-CHOICE SECTION. Please make sure your name is on: - the Datalink form - this question paper a nd tho worked Problem paper

Explanation / Answer

23

C

on reaching the terminal velocity the velocity beome constant. So acceleration decreases and velocity increases.

24

A

At terminal velocity, acceleration is zero so force must balance each other.
