A javelin thrower throws his javelin 32 m/s. She throws it with an angle of 45 degrees above the horizontal. How long is it in the air?

(Can you show it with the math? i don't really understand. )

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

a is the best answer your welcome

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.
