Hi there!

This collision is an example of an inelastic collision since kinetic energy is lost from the collision.

We can represent this using the conservation of momentum formula:

m1v1 + m2v1 = m1vf + m2vf

Where:

m1 = blue ball

m2 = green ball

We know that the final velocity of the blue ball is 0, so:

m1v1 + m2v1 = m2vf

Rearrange to solve for the speed of the green ball:

(m1v1 + m2v1)/m2 = vf

Plug in given values:

((0.15 · 3) + (0.15 · 2)) / 0.15 = 5 m/s

A compressed gas cylinder containing 1.50 mol methane has a volume of 3.30 L. What pressure does the methane exert on the walls

sweet-ann [11.9K]

Answer:

P=11.126 atm

Explanation:

We are given that a compressed gas cylinder containing 1.50 mol methane

Volume of methane in a gas cylinder =3.3 L

Temperature = $25^{\circ}=25+273.15=298.15 K$

We have to find the pressure exert by gas on cylinder

Using ideal gas equation

PV =nRT

Where R= gas constant=0.0821 L-atm/K mol

Substitute all given values

Then we get

$P\times 3.3=1.5\times 0.0821\times 298.15$

$P=\frac{36.717}{3.3}$

P=11.126 atm

Hence, the pressure exert by the gas on cylinder =11.126 atm

Three students each hold basketballs with the same masses at varying heights. One basketball is held 2 feet above the ground. An

Advocard [28]

The Basketball with the greatest gravitational potential energy is : Basketball 4 feet above the ground ( c )

<u>Given data :</u>

masses = constant

H₁ = 2 ft

H₂ = 3 ft

H₃ = 4 ft

g = 9.81 m/s²

<h3><u>Procedure to determine the basketball with the greatest gravitational P.E </u></h3>

we will apply the equation below

Gravitational potential energy ( U ) = mgh

For ball 1

U = 2 * 9.81 = 19.62

For ball 2

U = 3 * 9.81 = 29.43

For ball 3

U = 4 * 9.81 = 39.24

From the calculations the basketball with the greatest gravitational potential energy is the basketball at 4ft above the ground
