Which are characteristics of electromagnetic waves? Check all that apply.
They travel only through matter.
Waves with a higher frequency have a shorter wavelength.
o Waves with a higher frequency have a longer wavelength.
They all move at the same speed.
They can travel through space.

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

c) power lifting, will be your answer.
