Question

Выразите кинетическую энергию тела через массу m и импульс p

Answer 1

P = mV
P^2 = m^2 *V^2
P^2/2*m = m*V^2/2 = E к
Ответ   Ек = P^2/2*m  -  кинетическая энергия

Answer 2

Kinetic Energy of an Object in Terms of Mass and Momentum

The kinetic energy (E) of an object can be expressed in terms of its mass (m) and momentum (p) using the following formula:

E = p^2 / (2m)

Where: - E represents the kinetic energy of the object. - p represents the momentum of the object. - m represents the mass of the object.

This formula shows that the kinetic energy of an object is directly proportional to the square of its momentum and inversely proportional to its mass.
