LeBron James runs 260 meters East, then realized he dropped is basketball. He turns around and walks 54 meters West until he finds his ball. It takes him 45 seconds for the full trip. How far away is he from where he started?

206 meters East

Explanation:

Assuming that the starting point of Lebron James 0. He ran from point 0 to 260 meters in the Eastern direction. His displacement is now 260 meters to the East.

He then turned from the Eastern to the Western direction - opposing directions - and then walked 54 meters to find his ball. His displacement from the starting point will now be:

260 - 54 = 206 meters in the Eastern direction.

wavelength divides in half and speed stays the same.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
