Make your bubble juice. Mix 1 gallon of water with 2/3 cup dishwasher soap. 2. Tape the plastic lid over the end of the flashlight that the light shines from. 3. Turn on the flashlight and hold it so the light shines straight up. 4. Dip your finger in the bubble juice and wet the lid. Put a spoonful of bubble juice on the lid. 5. With a straw, blow one big bubble in the juice to make a bubble dome over the lid. 6. Watch the swirling colors until your bubble pops. 7. What colors did you see. Record this in your data table. 8. Repeat 2 more times.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

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
