Acar starts from rest and speeds up at 2.2m/s^2 after the traffic light turns green , how far will it have gone when it os traveling at 18m/s?

The displacement of the car, S = 396 m

Explanation:

Given data,

The acceleration of the car, a = 2.2 m/s²

The initial velocity of the car, u = 18 m/s

Using the III equations of motion,

                S = ut + ½ at²

Substituting the given values in the above equation

                S = 18 (2.2) + ½ x 2.2 x (18)²

                S = 396 m

Hence, the displacement of the car, S = 396 m

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

change tension
