for each situation, you need to determine if the object has ke or gpe or both. then find their values. be sure to include the correct units. 1. a 2-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:

A 2-kg bowling ball sits on top of a building that is 40 meters tall.

it is sitting there so it has no KE

it is sitting on top of a 40-m bldg so it has GPE

GPE = mass x gravity x height

= 2 x 9.8 x 40

= 784N

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds
