Question

The escape velocity of a bullet from the surface of planet y is 1599.0 m/s. Calculate the escape velocity from the surface of planet x if the mass of planet x is 1.45 times that of y, and its radius is 0.863 times the radius of y?

Answer 1

To calculate the escape velocity from the surface of planet x, we can use the formula for escape velocity, given the mass and radius of planet x compared to planet y.

Step-by-step explanation:

To calculate the escape velocity from the surface of planet x, we can use the formula for escape velocity:

Ve = sqrt((2GM)/r)

where Ve is the escape velocity, G is the gravitational constant, M is the mass of the planet, and r is the radius of the planet.

Given that planet x has a mass 1.45 times that of planet y, and its radius is 0.863 times the radius of y, we can write the equation as:

Ve,x = sqrt((2(G)(1.45My))/(0.863ry))

To find the escape velocity from planet x, we need to know the values of G, My, and ry.
