A2-kg bowling ball sits on top of a building that is 40 meters tall.

circle one: ke / gpe / both

show your work for finding the values of each type of energy the object has:

Step-by-step explanation:

1.

The ball is not moving and is at a height above the ground so it has only potential energy.

P.E = 2 x 9.81 x 40

P.E = 784.8 J

2.

The ball is moving and has a height above the Earth's surface so it has both kinetic and potential energy.

P.E = same as part 1 = 784.8 J

K.E = 1/2 x 2 x 5²

K.E = 25 J

3.

The ball has no height above the Earth's surface and is moving so it has only kinetic energy.

K.E = 1/2 x 2 x 10²

K.E = 100 J

4.

50000 = 1/2 x 1000 x v²

v = 10 m/s

5.

39200 = 200 x 9.81 x h

h = 20.0 m

6.

12.5 = 1/2 x 1 x v²

v = 5 m/s

98 = 1 x 9.81 x h

h = 10.0 m

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
