a)On a flat surface on an airless planet, a projectile is fired from a rover and lands 40 seconds later. If the launch speed of the projectile is doubled how many seconds will it take to land? Why?
b)On a flat surface on an airless planet, a projectile is fired from a rover and travels for 80 meters before landing. If the launch speed is doubled how far will it go? Why?

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)
