Remark
Always write down your givens and what you want to find. The formula you use for such questions will suggest itself if you do this.
Givens
a = 3.0 m/s^2
vi = 0 I presume that's that the question assumes.
vf = 33 m/s
You want d
Formula
vf^2 = vi^2 + 2*a*d
Solution
33^2 = 0^2 + 2 * 3 * d
1089 = 6*d
d = 1089/6
d = 181.5 meters
The best answer is D) Inertia
Inertia is the word assigned to the Newtonian law of motion that an object in motion tends to stay in motion, in a straight line and in the same direction at the same speed, as long as no other forces are acting on it.
In deep space, there is no air resistance or any other force that would change the ship's velocity, so the law of inertia would keep it moving at the same speed forever.
Answer:
The moon's gravity pulls the Earth to make tides.
Explanation:
The Moons Gravity Pulls On The Earth With Different Strenght Making High Tide And Low Tide.

Answer:
4.674 cm
Explanation:
refractive index of ice μ₁ = 1.309
refractive index of quartz μ₂ = 1.544
Velocity of light in ice v₁ = c/μ₁
= 3 x 10⁸ / 1.309
= 2.292 x 10⁸
Velocity of light in quartz v₂ = c/μ₂
= 3 x 10⁸ / 1.544
= 1.943 x 10⁸
Total time taken by light to pass through ice
= 2.12 x 10⁻²/ (2.292 x 10⁸ )
= .92 x 10⁻¹⁰ s
Total time taken by light to pass through quartz
= 1.24 x 10⁻²/ (1.943 x 10⁸ )
= .638 x 10⁻¹⁰ s
Total time taken
= .92 x 10⁻¹⁰ + .638 x 10⁻¹⁰
= 1.558 x 10⁻¹⁰ s
velocity of light in vacuum
= 3 x 10⁸ m /s
distance travelled in 1.558 x 10⁻¹⁰ s
= 3 x 10⁸ x 1.558 x 10⁻¹⁰
= 4.674 x 10⁻² m
4.674 cm
