Consider the motion of a 4.00-kg particle that moves with potential energy given by U(x) = + a) Suppose the particle is moving w
gtnhenbr [62]

Correct question:

Consider the motion of a 4.00-kg particle that moves with potential energy given by

U(x) = \frac{(2.0 Jm)}{x}+ \frac{(4.0 Jm^2)}{x^2}

a) Suppose the particle is moving with a speed of 3.00 m/s when it is located at x = 1.00 m. What is the speed of the object when it is located at x = 5.00 m?

b) What is the magnitude of the force on the 4.00-kg particle when it is located at x = 5.00 m?

Answer:

a) 3.33 m/s

b) 0.016 N

Explanation:

a) given:

V = 3.00 m/s

x1 = 1.00 m

x = 5.00

u(x) = \frac{-2}{x} + \frac{4}{x^2}

At x = 1.00 m

u(1) = \frac{-2}{1} + \frac{4}{1^2}

= 4J

Kinetic energy = (1/2)mv²

= \frac{1}{2} * 4(3)^2

= 18J

Total energy will be =

4J + 18J = 22J

At x = 5

u(5) = \frac{-2}{5} + \frac{4}{5^2}

= \frac{4-10}{25} = \frac{-6}{25} J

= -0.24J

Kinetic energy =

\frac{1}{2} * 4Vf^2

= 2Vf²

Total energy =

2Vf² - 0.024

Using conservation of energy,

Initial total energy = final total energy

22 = 2Vf² - 0.24

Vf² = (22+0.24) / 2

Vf = \sqrt{frac{22.4}{2}

= 3.33 m/s

b) magnitude of force when x = 5.0m

u(x) = \frac{-2}{x} + \frac{4}{x^2}

\frac{-du(x)}{dx} = \frac{-d}{dx} [\frac{-2}{x}+ \frac{4}{x^2}

= \frac{2}{x^2} - \frac{8}{x^3}

At x = 5.0 m

\frac{2}{5^2} - \frac{8}{5^3}

F = \frac{2}{25} - \frac{8}{125}

= 0.016N

When dealing with the conservation of momentum, does direction matter?
allochka39001 [22]

Answer:

Momentum is conserved in all three physical directions at the same time.

Explanation:

There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero.

4. A truck has four times the mass of a car and is moving with twice the speed of the car.
slamgirl [31]

Answer:

Relation between kinetic energy of truck and kinetic energy of car is given as

K_t = 16 K_c

Explanation:

As we know that mass of truck is four times the mass of car

m_t = 4 m_c

and the speed of truck is double that of speed of car

v_t = 2v_c

now we have kinetic energy of the truck is given as

K_t = \frac{1}{2}m_t v_t^2

similarly kinetic energy of car is given as

K_c = \frac{1}{2}m_cv_c^2

now from above two equations we have

\frac{K_t}{K_c} = \frac{\frac{1}{2}m_tv_t^2}{\frac{1}{2}m_cv_c^2}

\frac{K_t}{K_c} = 4(4) = 16

so we have

K_t = 16 K_c
