What is the magnitude of the orbital velocity of the planet mercury (orbit radius =5.79× 10 7 km , orbital period = 88.0 days)?

The orbital speed of the planet mercury can be calculated by the formula,

Here, R is the orbital radius and T is the orbital time.

Given and (in second

Substituting these values in above formula we get,

Thus, the orbital velocity of the planet mercury is 47.9 km/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
