Question

по горизонтальному столу катится шарик массой 50г с постоянной скоростью 2м.с.чему равна его кинетическая энергия?

Answer 1

Calculation of Kinetic Energy

To calculate the kinetic energy of a rolling ball, we can use the formula:

Kinetic Energy (KE) = (1/2) * mass * velocity^2

Given the following information: - Mass of the ball = 50 grams = 0.05 kg - Constant velocity of the ball = 2 m/s

We can substitute these values into the formula to find the kinetic energy:

KE = (1/2) * 0.05 kg * (2 m/s)^2

Simplifying the equation:

KE = (1/2) * 0.05 kg * 4 m^2/s^2

KE = 0.1 Joules

Therefore, the kinetic energy of the ball rolling with a mass of 50 grams and a constant velocity of 2 m/s is 0.1 Joules.
