Directions: 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. 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 rolls at a speed of 5 m/s on the roof of the building that is 40 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 rolls at a speed of 10 m/s on the ground. circle one: ke / gpe / both show your work for finding the values of each type of energy the object has: a 20-kg child is tossed up into the air by her parent. the child is 2 meters off the ground traveling 5 m/s. circle one: ke / gpe / both show your work for finding the values of each type of energy the object has: part 2: finding speed and height using energy directions: use the ke and gpe equations to solve for speed or height depending on the situation. a 1,000-kg car has 50,000 joules of kinetic energy. what is its speed? a 200-kg boulder has 39,200 joules of gravitational potential energy. what height is it at? a 1-kg model airplane has 12.5 joules of kinetic energy and 98 joules of gravitational potential energy. what is its speed? what is its height?
