Space propulsion project
goal: choose what type of propulsion system you would like to use for your spaceships trip from earth to the astroid belt beyond mars. you are free to choose any of the ship types but you must calculate the time from earth to the astroid belt. you must also calculate the final velocity.
mission specs:
drive types, propulsion force (n), mass (kg)
ion drive, 0.1 n, 20,000 kg
space sail, 1 n, 25,000 kg
conventional rocket, 30,000 n, 40,000 kg

other needed info: the ship is in an orbit around the earth beyond the moon. you can assume the starting velocity of the ship is 0 and the earth and suns pull on the ship is negligible. the asteroid belt is about 2.8 au from the sun or 1.8 au from the earth. this is a distance if about 2.5x10^11 m

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

i don't understand. explain it clearly

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
