Which of the following is NOT an example of a situation when you might need to add vectors?

A.) You know your initial speed and final speed in a car moving in a straight line, and you want to know by how much your speed changed.

B.) Your workmates are having a tug-of-war, and you want to know who is likely to win based on the forces each team can apply.

C.) A person is walking on an escalator and you want to calculate the total velocity.

D.) An object is accelerating in two directions due to its motion in a car, and its orbit around the Earth, and you want to know the total acceleration.

E.) Several people are pushing on an object, and you want to know which way it will accelerate (if at all).

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
