Constant Acceleration: Space Travel Speeds

CLMECH-1IJWZM

When traveling between planets, it has been suggested that artificial gravity could be provided by constantly accelerating the rocket until the half-way point is reached and then the ship would decelerate for the remainder of the trip. Suppose a ship is to make a $1.00\times 10^9\,km$ trip.

If it accelerates at $9.81\,\frac{m}{s^2}$ from rest to the halfway point and then decelerates for the remainder of the trip, What would the maximum ship speed be?

A

$4.43\times 10^6\,\frac{m}{s}$

B

$3.13\times 10^6\,\frac{m}{s}$

C

$2.21\times 10^6\,\frac{m}{s}$

D

$9.81\times 10^6\,\frac{m}{s}$
