The velocity of the water leaving the sluice box was 90 centimeters per second (cm/s) . state the diameter of the largest particle that could be found in the tailings

b.

explanation:

10.0

15.3 cos 65 degrees trig

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

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
