A student drops a ball from a height of 40.0m. If the ball increases speed at a uniform rate of 9.81m/s2, determine all unknowns and answer the following
questions.
How long did the ball remain in the air?
What was the ball's speed just before striking the ground?

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?

Arrange the images in order to show how lake-effect snow occurs.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
