Tierra pushes on a 1000 N crate with a force of 200 N to the right. The crate does not move. What are both the normal force and the force of friction?

A. FN = 200 N up; FF = 1000 N left
B. FN = 1000 N down; FF = 200 N right
C. FN = 1000 N up; FF = 200 N right
D. FN = 1000 N up; FF = 200 N left

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
