The captain orders his starship to accelerate from rest at a rate of "1 g" (1 g = 9.8 m/s2). How many days does it take the starship to reach 10% the speed of light? (Light travels at 3.0 × 108 m/s.)

The  days it will take the starship to reach 10% of speed of light is approximately 35 days.

Explanation:

Given;

acceleration of the starship, a = 9.8 m/s²

speed of light is given as, v = 3.0 × 10⁸ m/s

10% of speed light = 0.1 x 3.0 × 10⁸ m/s = 3.0 × 10⁷ m/s

Apply kinematic equation;

acceleration is the time rate of change in velocity.

a = Δv/t

t = Δv/a

Substitute the given values and solve for time

t =  (3.0 × 10⁷)/9.8

t = 3061224.4898 seconds

Therefore, the  days it will take the starship to reach 10% of speed of light is approximately 35 days.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
