The waves in some amusement park wave pools are controlled by regularly spaced bursts of air. Chang-
ing the timing and strength of these air bursts also
changes the characteristics of the waves that result.
Predict List and describe four wave
characteristics. Which characteristic(s) do you
think would change if the air bursts were
stronger? Which would change if more air bursts
came in a shorter amount of time? Explain.

the answer would be   dignified - apex

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

0.93xc=0.93x3x10^8m/s
