G What is the frequency of the train whistle as heard by a passenger on the train? n alert physics student stands beside the tracks as a train rolls slowly past. She notes that the train whistle has a frequency of 465 Hz as the train approaches her and a frequency of 445 Hz as the train moves away from her. The speed of sound is 343 m/s. While waiting for her own train to arrive, the student performs some ca

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

i think it would be 5

that the claims meet official rules.

don't misinterpret the claims

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.
