A car moving at a speed of 8.0 m/s merges onto the highway and accelerates at a rate of 3.0 m/s2. How fast is it moving after travelling for 54 meters?

As per the data in Question,

Using the third equation of motion :-

Substituting the respective values ,

⇒ 2as = v² - u² .

⇒ 2 × 3 × 54 = v² - 8²

⇒ 324 + 64 = v² .

⇒ v² = 388.

⇒ v = √388 .

⇒ v = 19.69 m/s ≈ 20m/s .

Hence the required answer is 19.69 m/s.

b.transmitters send radio waves, and receivers capture radio waves.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
