5. A car accelerates from rest down a highway at 6 m/s2 for 5 seconds. What distance did the car travel during acceleration?

Mumz [18]

Answer:

75 m

Explanation:

The distance x for a uniform acceleration is given by the equation:

$x = \frac{1}{2}at^{2}+v_ot+x_o$

The given values are:

a = 6 m/s², t = 5 s, v₀ = 0, x₀ = 0

What is the gravity of sombrero galaxy compared to earth?

Aleksandr [31]

the Sombrero galaxy, is one of the largest mosaics ever assembled from Hubble observations. The hallmark of the nearly edge-on galaxy is a brilliant, white, bulbous core encircled by thick dust lanes comprising the spiral structure of the galaxy. This dust lane is the site of star formation in the galaxy. The center of M104 is thought to be home to a massive black hole. I hope this helped
