Answer:
Yellow, green, polka dot and white jerseys
Explanation:
Tour de France is the biggest bicycle race in the world held at France over a period of 23 days. At the end of each day of racing they give to the certain riders FOUR different colored jerseys:
- The yellow jersey is given to the overall winner at each stage, this shows the rider who was the best in the previous stage.
- The green jersey is given to the best sprinter of each stage,
- The polka dot jersey is given to the rider who first reach the crest of designated hills and mountains at each stage.
- The white jersey is given to the fastest rider at each stage under 25 years at the beginning of the racing year.
At the end of the competition, the total points are counted and the different jerseys are given to the overall winners.
Answer:
d = 4 d₀o
Explanation:
We can solve this exercise using the relationship between work and the variation of kinetic energy
W = ΔK
In that case as the car stops v_f = 0
the work is
W = -fr d
we substitute
- fr d₀ = 0 - ½ m v₀²
d₀ = ½ m v₀² / fr
now they indicate that the vehicle is coming at twice the speed
v = 2 v₀
using the same expressions we find
d = ½ m (2v₀)² / fr
d = 4 (½ m v₀² / fr)
d = 4 d₀o
Since both hv same mass and elsstic collision, so their velocity will exchange. Bob A will stop and bob B will move with speed of A just before the collision.
Speed will be = squreroot ( 2*g*L)
L is length of pendulum
