A projectile is launched from the surface of a planet (mass = 5x1024, radius = 1.1x106). What minimum launch speed is required if the projectile is to rise to a height above the surface of the planet equal to half the radius? Disregard any dissipative effects of the atmosphere. use WNC = 0= ΔU + ΔK = −GMm[(1/rB)-(1/rA)]+(1/2)m(vf^2-v0^2)

Consider an airless, non-rotating planet of mass M and radius R. An electromagnetic launcher standing on the surface of this planet shoots a projectile with initial velocity v0 directed straight up. Unfortunately, due to some error, v0 is less than the planet’s escape velocity ve; specifically, v0 = 0.701 ve. Unable to escape the planet’s gravitational pull, the projectile rises to a maximal height h above the ground, then falls back to the ground. Calculate the ratio h R of...

The small spherical planet called "Glob" has a mass of 7.20×1018 kg and a radius of 6.29×104 m. An astronaut on the surface of Glob throws a rock straight up. The rock reaches a maximum height of 1.20×103 m, above the surface of the planet, before it falls back down. What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction. G = 6.67×10-11 Nm2/kg2.)...
