A12,000-kg lunar landing craft is about to touch down on the surface of the moon, where the acceleration due to gravity is 1.6 m/s2. at an altitude of 158 m the craft's downward velocity is 16.9 m/s. to slow down the craft, a retrorocket is firing to provide an upward thrust. assuming the descent is vertical, find the magnitude of the thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface. in newtons.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
