Answer:
3.2 m
Explanation:
The equation to use to solve this problem is:
where
is the final velocity
is the initial velocity
a is the acceleration
is the distance covered
For the particle in free-fall in this problem, we have
(it starts from rest)
(acceleration due to gravity)
By re-arranging the equation, we can find the distance travelled:
Slide with her left foot. hope this is helpful
Velocity is distance over time
. If it wants it in km/h you're good to go otherwise if its m/s you need to convert km to m by multiplying 30 by 1000 and t in hours to seconds by multiplying 0.5 by 3600.
Answer:
Explanation:
a) Power consumption is 4100 J/min / 60 s/min = 68.3 W(atts)
work done raised the potential energy
b) 75(9.8)(1000) / (3(3600)) = 68.055555... 68.1 W
c) efficiency is 68.1 / 68.3 = 0.99593... or nearly 100%
Not a very likely scenario.
Answer:
1.846....hours
Explanation:
since if we divide 12 km or just 12 by 6.5 we will get this number meaning that this is how long it would take someone
