Question

M=7 кг. V= 4,5 % Eк -?​

Answer 1

Ответ:7кг*0,45²/2=0.7

Объяснение:

Ек=mV²/2

Answer 2

To calculate the kinetic energy (Ek) of an object, you need to multiply its mass (M) by the square of its velocity (V) and divide the result by 2.

Given: M = 7 kg (mass) V = 4.5% (velocity)

First, convert the percentage velocity to decimal form: V = 4.5 / 100 = 0.045

Now, calculate the kinetic energy (Ek): Ek = (M * V^2) / 2

Substituting the given values: Ek = (7 * 0.045^2) / 2 Ek = (7 * 0.002025) / 2 Ek = 0.014175 / 2 Ek = 0.0070875

The kinetic energy (Ek) of the object is approximately 0.0070875 Joules.
