Question

how to find kinetic energy with only mass and height? (what to do if velocity is not given)?​

Answer 1

Answer:

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

Hope it helps!!

Please mark me as brainliest

Answer 2

Answer:

We cannot.

We need mass and velocity.

You have not said anything about the object in questions motion.

Is it sitting still, about to be dropped? Well then its KE = 0.

Is it in motion? Well then its KE = 1/2 * m* v^2

Its height is utterly irrelevant to its kinetic energy.

Now - if instead you were to ask:

An object near the surface of the Earth is dropped from a height h. What is its KE immediately before impact?
