Fs=kx k=spring constant x=displacement (stretch) of the spring 2. In a dart gun, the spring that launches the dart has a spring constant of 2400 N/m. When you push the dart into the gun, it squeezes the spring until it
is 0.055 m long. How much force does the spring exert on the dart?

Please help me

unlike poles attract

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
