A1,000 kg car has 50,000 joules of kinetic energy. what is it’s speed

50,000/1,000

this is what you have to do you have to divide the killigrams by the juels

½mv²= KE  

½(1000)?²= 50000

500*?²= 50000

/500            /500

? ²=100

Square root  

?= 10

10 m/s is you answer

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
