Mount Saint Helens is a popular place for many mountain climbers. The current official elevation of the summit (highest point) is 29,029 ft. Which of the following would be the greatest challenge for mountain climbers to adjust to as they climb up the mountain?

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

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

what is the actual question though?
