During the Egg Drop lab sim you manipulated several variables like height, egg mass and impact surface. Which varible combination would produce the smallest force of impact on the egg?
Large time of impact and small speed at impact
Small time of impact and small speed at impact
Large time of impact and large speed at impact
Small time of impact and large speed at impact

mass and volume are the answers you are looking for

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
