Answer:

Horse/Speed

55 mph

rounded to the tenth? either 60 or 50

but 350 would stay like that i believe!

A 7.0- g bullet is fired into a 1.5- kg ballistic pendulum.The

777dan777 [17]

Answer:

the initial velocity of bullet is u = 330.335 m /s

Explanation:

given,

mass of bullet(m) = 7 g

Mass of pendulum ( M ) = 1.5- kg

The bullet emerges from the block with a speed (V) = 200 m/s

The maximum height ( h ) = 12 cm.

Let the initial speed of the bullet be ' u '

Apply, Law of conservation of momentum :

m u = ( m + M ) V ...............................(1)

Apply, Law of conservation of Energy :

$\dfrac{1}{2}( m + M ) V^2 = ( m + M )g h$ ...............(2)

From equation (1) and equation (2) , we have

$u = \dfrac{m + M}{m}V$

But V = √2gh

$u=\dfrac{m + M}{m}\times \sqrt{2gh}$

$u=\dfrac{0.007+1.5}{0.007}\times \sqrt{2\times 9.81\times 0.12}
$

u = 330.335 m /s

hence, the initial velocity of bullet is u = 330.335 m /s

he measured flow rate of water through a 20 mm diameter pipe is 75 L/min. What is the average velocity (in m/s) of water flowing

Masteriza [31]

Answer:

Average velocity of water flow through the pipe = 3.98 m/s

Explanation:

Diameter of pipe = 20 mm

Discharge = 75 L/min

We know that

Discharge = Area x Velocity

$\texttt{Area of pipe}=\frac{\pi d^2}{4}=\frac{\pi \times (20\times 10^{-3})^2}{4}=3.14\times 10^{-4}m^2$

Discharge = 75 L/min

$=\frac{75\times 10^{-3}}{60}=1.25\times 10^{-3}m^3/s$

Substituting

$1.25\times 10^{-3}=3.14\times 10^{-4}\times V\\\\V=3.98m/s$

Average velocity of water flow through the pipe = 3.98 m/s
