Question

A roller coaster is at the top of a 72 m hill and weighs 134 kg. The coaster (at this moment) has potential____________ energy. Calculate it.

Answer 1

At the top of a hill, it's moving at a speed of 3 meters/second. After reaching the bottom of the hill, its speed doubles. The car's kinetic energy at the bottom is (half, double, triple or quadruple) its kinetic energy at the top.

Answer 2

Answer:

At the top of a hill , it's moving at a speed of 3 meter / second. After reaching the bottom of the hill , it's speed double , The car kinetic energy

at the bottom is ( half ,double,triple Or quadruple ) it's kinetic energy at the top

hope it help uh!!☺✌☃️
