Explanation:
<h2>Speed is the rate of change of distance with time.</h2>
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.

Explanation:
Convert the time to seconds : 5minutes × 60 = 300seconds
Acceleration = Velocity / Time
Acceleration = 20m/s / 300s
Acceleration = 0.067m/s²
Distance = Velocity × Time
Distance = 20m/s × 300seconds
Distance = 6000m
I heard that the answer is convective zone, not sure if that’s right but i hope i helped :)
This is so sweet I wish the same back to you :))
