Distance = 6 km south 60 minutes What was the average velocity

Physics

For this case we have to by definition:

v = \frac {x} {t}

Where:

v: Velocity

x: Distance traveled

t: Time

According to the data we have:

x = 6 \ km = 6000 \ m\\t = 60 \ min = 3600 \ s

So:

v = \frac {6} {60} = 0.1  \frac {km} {min}

Equivalent to:

v = \frac {6000} {3600} = 1.67 \frac {m} {s}

Answer:

0.1 \frac {km} {min}

v = x/t

v = average velocity, x = displacement, t = elapsed time

Given values:

x = 6km south, t = 60min

Plug in and solve for v:

v = 6/60

v = 0.1km/min south

madam [21]

Answer:

Light does not need a medium to travel travel through, but since waves must have a medium to vibrate, sound is not created where no air is present.

Grindstone: Rotational Dynamics and Kinematics You have a grindstone (a disk) that is 133.0 kg, has a 0.635 m radius, and is tur
Colt1911 [192]

Answer:

Ff = 839.05 N

Explanation:

We can use the equation:

Ff = μ*N

where <em>N</em> can be obtained as follows:

∑ Fc = m*ac   ⇒   N - F = m*ac = m*ω²*R    ⇒  N = F + m*ω²*R

then if

F = 32 N

m = 133 Kg

R = 0.635 m

ω = 95 rev /min = (95 rev / min)(2π rad / 1 rev)(1 min / 60 s) = 9.9484 rad /s

we get

N = 32 N + (133 Kg)*(9.9484 rad /s)²*(0.635 m) = 8390.53 N

Finally

Ff = μ*N = 0.10*(8390.53 N) = 839.05 N

Work done by a gravitational force by lowering the bucket into the well is
katovenus [111]

Answer:

when we lower a bucket into a well to fetch water, the work done by gravity is positive since force and displacement are in the same direction.
