A large container contains a large amount of water. A hole is drilled on the wall of the container, at a vertical distance h = 0

hammer [34]

Speed can be found through the application of concepts related to potential energy and kinetic energy, for which you have

$KE = PE$

$\frac{1}{2}mv^2 = mgh$

Where,

m = mass

v = Velocity

g = Gravitational acceleration

h = Height

Re-arrange to find the velocity we have,

$v^2 = 2gh$

$v = \sqrt{2gh}$

$v = \sqrt{2(9.8)(0.54)}$

$v = 3.253m/s$

Therefore the speed at which water squirts out of the hole is .3253m/s

Help meeeeeeeeeeeeee! please show work! In a collision, Kara Less who was traveling at 11 m/s while texting in her 1300 kg car,

raketka [301]

The impulse experienced is -18,000 kg m/s

Explanation:

The impulse exerted on an object is equal to the change in momentum of the object. Mathematically:

$I=\Delta p = m(v-u)$

where

m is the mass of the object

v is the final velocity of the object

u is the initial velocity

$\Delta p$ is the change in momentum

I is the impulse

In the collision in this problem,

m = 1300 kg is the mass of the car

u = 11 m/s is the initial velocity

v = -2.5 m/s is the final velocity (negative, since it is in the opposite direction)

Substituting, we find

$I=(1300)(-2.5-11)=-17,550 kg m/s$

So the closest choice is

-18,000 kg m/s

A hailstone traveling with a velocity of 43 meters/second comes to a virtual stop 0.28 seconds after hitting water. What is the

lisabon 2012 [21]

Magnitude of acceleration = (change in speed) / (time for the change) .

Change in speed = (ending speed) - (starting speed)

= zero    - (43 m/s)

=    -43 m/s .

Magnitude of acceleration = (-43 m/sec) / (0.28 sec)

      = (-43 / 0.28) (m/sec) / sec

      =    153.57... m/s²

      = 1.5... x 10² m/s² .

Seema knows the mass of a basketball. What other information is needed to find the ball’s potential energy?

adelina 88 [10]

Potential energy can be found using this formula:

PE= m * g * h

where:

PE= potential energy

m=mass

g=gravitational acceleration constant (9.8 m/s^2)

h= height

So your answer is height because you also use the gravitational constant.
