Atrain 471 m long is moving on a straight track with a speed of 75.1 km/h. the engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 15 km/h. assuming constant acceleration, determine how long the train blocked the crossing. disregard the width of the crossing. answer in units of s.

Choose each of the settings that follow and list them below do it ill mark brainliest first object= position= speed= acceleration= second object= position= speed= acceleration=

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.
