Answer 1

1)
Е(к)=mv^2/2=80000г•25м/с^2/2=1000000=1000кДж

Answer 2

1. To calculate the kinetic energy (E(к)) of an object, you can use the formula:

E(к) = (1/2) * m * V^2

where: m = mass of the object (in kilograms) V = velocity of the object (in meters per second)

Given: m = 80 kg V = 5 m/s

Substituting the values into the formula:

E(к) = (1/2) * 80 kg * (5 m/s)^2

E(к) = 0.5 * 80 kg * 25 m^2/s^2

E(к) = 1000 kg * m^2/s^2

Therefore, the kinetic energy (E(к)) is 1000 kg * m^2/s^2.

2. It seems like you have two formulas and want to calculate certain quantities. Could you please clarify the variables and provide the specific values you have for each variable?
