Answer:
The left train travels 2378 m until it reaches the meeting point.
Explanation:
The equation for the position of the trains is the following:
x = x0 + v · t
Where:
x = position at time t
x0 = initial position
v = velocity
t = time
If we place the origin of the frame of reference at the initial position of the left train, the right train will be at an initial position of 4744. 6 m relative to the left train. The velocity of the right train will be negative because it will be heading towards the origin.
At the meeting point, the position of both trains is the same:
x left train = x right train
x0₁ + v₁ ·t = x0₂ + v₂ · t
0m + 29 m/s · t = 4744.6 m - 29 m/s · t
58 m/s · t = 4744.6 m
t = 4744.6 m / 58 /s
t = 82 s
The position of the left train at that time will be:
x = x0 + v · t
x = 0 m + 29 m/s · 82 s
x = 2378 m
The left train travels 2378 m until it reaches the meeting point.
Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. ... The moon appears full when the Earth is between the moon and the sun
Answer:
4 kg of force
Explanation:
Force = (mass x distance to fulcrum) / length of fulcrum to end
Subsitute values
F = (10 x 20)/50
F =4
Answer: <u>Centrifugal Force </u>
Explanation:
The force that pulls out from the center on a body in circular motion is called centrifugal force and it increases with acceleration. Centrifugal force results in strong outward pull on your vehicle.
C.
The kilogram SI unit is based off an original prototype that is kept in France. The prototype itself is based off the mass of water under special conditions for temperature as well as pressure.
