Question

Тело массой 1кг свободно падает с некоторой высоты . В момент падения на землю его скорость равна 10м\с . найдите его кинетическую энергию.

Answer 1

$E= \frac{mv^{2} }{2}= \frac{1*100}{2}=50$
Eк=50 Дж
Удачи!

Answer 2

Calculating Kinetic Energy of a Falling Object

To calculate the kinetic energy of the falling object, we can use the formula:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

Given: - Mass (m) = 1 kg - Velocity (v) = 10 m/s

Using the given values, we can calculate the kinetic energy of the falling object.

Calculation

Kinetic Energy (KE) = 0.5 * 1 kg * (10 m/s)^2

Kinetic Energy (KE) = 0.5 * 1 kg * 100 m^2/s^2

Kinetic Energy (KE) = 50 Joules

So, the kinetic energy of the falling object is 50 Joules.
