Answer:

Explanation:

a = 4ms⁻², Vf = 180 m/s & Vi = 140m/s

a = $\frac{Vf-Vi}{t}$

4 = $\frac{180-140}{t}$

t = 40/4

t = 10sec

To Measure Distance Use third Equation of Motion:

2aS = Vf²-Vi²

S = $\frac{180*180 - 140*140}{2(4)}$

S = 12800/8 = 1600m

Why does the Polaris appear to remain stationary in the night sky when other stars show an apparent pattern?

yanalaym [24]

Because one pole of the Earth's axis of rotation (the North one) points
almost exactly toward Polaris.

If Polaris had a pimple or a bump somewhere on its edge, you'd see
the bump rotate around the whole edge, like a clock, once a day. But
the whole star appears to stay in one place, because our axis points to it.
