Kinetic energy is the energy of motion.

The formula for kinetic energy is given as

KE = (0.5) m v²

where m = mass of object , v = speed of object.

an object having some speed and mass will have kinetic energy while an object at rest will not have any kinetic energy since the speed of object at rest is zero.

Since at rest speed is zero. an object has kinetic energy only when it is in motion.

Taylor Swift weighing 794 N gets on an elevator. The elevator uses 313 W of power to lift the person 22.0 m. How much time did t
mezya [45]

Answer:

55.80s

Explanation:

Power is calculated using the expression

Power = Work done/Time

Workdone= Force ×distance

Workdone = 794×22

Work done = 17468Joules

From the power formula

Time = Workdone/Power

Time = 17468/313

Time = 55.80seconds

The elevator takes 55.80seconds to life the Taylor

Explanation:

Data

mass = ?

Weight = 382 N

gravity = 9.81 m/s2

Formula

Weight = mass x gravity

mass = weight / gravity

mass = 382 / 9.81         substitution

mass = 38.93 kg           result

This isn’t homework related but what methods do you guys recommend for shifting realities ? .I’ve tried the raven method for wee
elena55 [62]

Answer:

subs

Explanation:

I've seen subliminals online that are supposed to help shifting. You could see for yourself if they work for you. You could probably also use the method where you act like you already have your desires and results. I have seen a lot of people act as if they have their desires and affirm it constantly. Ex: you want to lose weight, so you act as if you already are your desired weight and tell yourself that you are such and such weight, and don't contradict it by saying that you aren't. I hope that this helps.
