A natural satellite. Or just a satellite.
The tension in the cables as the elevator travel upwards is 1,960 N.
The given parameters:
- Mass of the elevator, m = 200 kg
<h3>Newton's second law of motion;</h3>
Newton's second law of motion states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The tension in the cables as the elevator travel upwards is calculated by applying Newton's second law of motion as shown below;
T = ma + mg
where;
- a is the acceleration of the elevator
- g is the acceleration due to gravity
At constant velocity, acceleration is zero (a = 0)
T = m(0) + mg
T = mg
T = 200 x 9.8
T= 1,960 N
Thus, the tension in the cables as the elevator travel upwards is 1,960 N.

You can usaly not feal it because the earth is moving and the plates aren't having any major change to the movement.
Let her initial velocity be U.
Let the width of the river be W.
She swims 3/5 the width of the river at U.
Remainder width = (1 - 3/5) = 2/5.
She then swims 2/5 the width with velocity U/2.
Average Speed = (Total Distance Traveled) / ( Total Time Taken).
Distance = Speed * time
time = Distance / Speed.
Time in first trip: = (3/5)W / U = 0.6W/U.
Time in second trip = (2/5)W / (U/2) = 0.4W / 0.5 U = 0.8W/U
Total Distance Traveled = W, width of the river.
Average Speed = W / (0.6W/U + 0.8W/U) = W / (1.4W/U)
= W * U / 1.4W
= U/1.4
= U * 10 / 14
= (5/7) U.
Therefore Average speed is (5/7) of the initial speed.
