How far (in meters) will you travel in 3 minutes running at a rate of m/s?

There are 60 seconds in 1 minute. So, 3 minutes is the same as 3×60=180 seconds. If you travel 6 m/s (meaning after 1 second, you've run 6 meters), then after 3 minutes (or 180 seconds), you have run 6×180=1080 meters.

a supertanker traveling at 7.2 m/s decelerates to a halt in 12 min. Calculate the magnitud of its average decelaration in meters

Nataliya [291]

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (0 m/s − 7.2 m/s) / (12 min × 60 s/min)

a = -0.01 m/s²

A fire hose 5 centimeters in diameter is used to fill a 225-liter bucket. If it takes 15 seconds to fill the bucket, what is the

Vika [28.1K]

I believe you ask about speed at the end of the hose:

The volume of the bucket is 225 liters which is equal to 225 $dm^{3}$ .
$V=225dm^{3}$
Hose's cross section can be counted with the typical circle's area formula (with diameter instead of radius, that's why you've got a fraction):
$A=3,14*\frac{d^{2}}{4}}=0,19625dm^{2}$

$225dm^{3}$ are filled within 15 second.

As the bucket is being filled you can say that it's volume is the volume of the water that flowed out of the hose, then:
$V=A*h$
The speed of the water can be counted with equation:
$v=\frac{h}{t}$
After extracting h from the volume's equation you get:
$v=\frac{V}{A*t}$
When you count the fraction you get the answer:
$v=76,43\frac{dm}{s}=0,7643\frac{m}{s}$

Odina walked down the hall at school from the cafeteria to the band room, a distance of 100.0m. A class of physics students

Nata [24]

Find distance she traveled:

100m -25m = 75m

58 seconds / 2 second intervals = 29

29 x 2.6m = 75.4 meters total.

if the distance wasn’t rounded the statement was False.

Answer: False
