what is the orbital speed for a satellite 3.5 x 10^8m from the center of mars? Mars mass is 6.4 x 10^23 kg

v = 349.23 m/s

Explanation:

It is required to find the orbital speed for a satellite from the center of mass.

Mass of Mars,

The orbital speed for a satellite is given by the formula as follows :

So, the orbital speed for a satellite is 349.23 m/s.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

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
