PE is related to the ability to do work, If an item is sitting on a shelf
it has potential energy relative to its position on the floor, However, if the object were to fall it would hit the floor with a KE equal to the PE that it had sitting on the shelf.

Explanation:
Speed= Distance/Time
5.0/2.58 = 1.937984496
= <em><u>1.94</u></em> m/s (<em><u>2dp</u></em>)
Explanation:
The distance traveled north ward = 2 miles
distance traveled south ward = 3miles
Displacement is the distance traveled in a specific direction. So, it depend on the start and finish point.
The displacement = 3 miles - 2miles = 1mile southward
Distance is the total length of path;
Distance = 3 miles + 2 miles = 5miles
here is the answer Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
