Question

ДАНО m=12кг u= 2 m/c ek = ?

Answer 1

Ответ:

Ek=mv^2 /2 => 12×4/2 = 24дж

Answer 2

To calculate the kinetic energy (ek), we can use the formula:

ek = (1/2) * m * u^2

Given: m = 12 kg (mass) u = 2 m/s (velocity)

Substituting the values into the formula:

ek = (1/2) * 12 kg * (2 m/s)^2

Calculating the values:

ek = (1/2) * 12 kg * 4 m^2/s^2 = 6 kg * 4 m^2/s^2 = 24 kg m^2/s^2

Therefore, the kinetic energy (ek) is 24 kilogram meters squared per second squared (kg m^2/s^2).
