At the start, a group of 10 skiers. Start one at a time, every 10 seconds. The speed of the skiers is approximately 3 m / s. What is the length of the chain?
n = 10.
t1 = 10 s.
V1 = 3 m / s.
L -?
The length of the chain L will be equal to the distance traveled by the first skier from the start to the exit of the last, tenth skier.
The first skier moved uniformly for a time t = t1 * (n – 1) with a speed V1.
The distance traveled by the first skier L is found by the formula: L = V1 * t = V1 * t1 * (n – 1).
L = 3 m / s * 10 s * (10 -1) = 270 m.
Answer: the length of the chain of skiers was L = 270 m.
