An elevator cab and its load have a combined mass of 1200 kg. Find the tension in the supporting cable when the cab, originally moving downward at 10 m/s, is brought to rest with constant acceleration in a distance of 35 m.

10044 N

Explanation:

The acceleration of the cab is calculated using the equation of motion:

v is the final velocity = 0 m/s in this question, since it is brought to rest

u is the initial velocity = 10 m/s

a is the acceleration

s is the distance = 35 m

Since it accelerates downwards, its resultant acceleration is

g is the acceleration of gravity.

The tension in the cable is

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

radiation

explanation:

heat is transmitted by radiation
