Which of the following is an example of potential energy?

Physics
1 answer:
Papessa [141]3 years ago
4 0

Answer:

A

Explanation:

potential energy is stored energy so the ball has potential energy to bounce or roll which would then have been converted to kinetic but the rest are in motion meaning energy is no longer stored but used in motion and therefore cannot be potential energy

A neutron is confined in a one-demensional potential box of width 5.0 x 10^-15 m. Calculate the minimum kinetic energy of the ne
kvv77 [185]

Answer:

E_1=1.31\times 10^{-12}\ J

Explanation:

Given that,

Width of a one dimensional potential box, x=5\times 10^{-15}\ m

The energy of a particle in one dimensional box is given by :

E_n=\dfrac{n^2h^2}{8mx^2}

h = Planck's constant

m = the mass of the proton

For minimum kinetic energy, n = 1

E_1=\dfrac{(6.63\times 10^{-34})^2}{8\times 1.67\times 10^{-27}\times (5\times 10^{-15})^2}

E_1=1.31\times 10^{-12}\ J

So, the minimum kinetic energy of the neutron is 1.31\times 10^{-12}\ J. Hence, this is the required solution.

A 0.80-kg soccer ball experinces an impulse of 25 N x s . Determine the momentum change of the soccer ball.
borishaifa [10]

If the impulse is 25 N-s, then so is the change in momentum.
The mass of the ball is extra, unneeded information.

Just to make sure, we can check out the units:

<u>Momentum</u> = (mass) x (speed) = <u>kg-meter / sec</u>

<u>Impulse</u> = (force) x (time) = (kg-meter / sec²) x (sec) = <u>kg-meter / sec</u>

A block is pulled across a table by a constant force of 9.20 N. If the mass of the block is 2.30kg, how fast will the block be m
kaheart [24]

Answer:

8\:\text{m/s}

Explanation:

From Newton's 2nd Law, we have \Sigma F=ma. Using this, we can find the acceleration of the object:

9.20=2.30a,\\a=\frac{9.20}{2.30}=4\:\mathrm{m/s^2}.

Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:

v_f=v_i+at,\\v_f=0+4(2),\\v_f=\boxed{8\:\text{m/s}}

*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.
