Select the characteristic(s) that match the properties of a diverging lens. Choose all that apply. It is thinner in the middle than at the edges.
It is thicker at the middle than at the edges.
It bends parallel rays of light so that they spread further apart.
It bends parallel rays of light so that they are focused at a point.

8 meters above the spring

i'm thinking more like energy

in physics zero. in muscle fatigue could be high

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
