Answer:
2.66 m/s² .
Explanation:
Initial velocity , u = 0 m/s
Final Velocity , v = 8 m/s
Time Taken , t = 3 s
So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²
Answer:
average velocity = 6.25m/sec
Explanation:
given data:
for unopened
height = 625 m
time = 15 sec
for opened
height = 356 m
time = 142 sec
Unopened:
Opened:
we know that
Total Average Velocity
average velocity
average velocity = 6.25m/sec
downward direction.
'N' is labelled 'runoff'. That's when the water is down. Streets are wet, worms come out of the ground, and water flows down the street to the sewer.
Answer:
the human body isn't very efficient at converting food into useful work. The human body is less than 5% efficient most of the time. The rest of the energy is converted to heat, which may or may not be useful, depending on how cool or warm a person wants to be.
Explanation:
Answer:
Explanation:
When at rest, initial velocity = 0
In 2 seconds, final velocity = 2 m/s
Acceleration = (final velocity - initial velocity) / time
= (2 - 0) / 2
= 1 m/s^2
