Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can mov

e the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
a
Moving the cart on Track 1 one space to the right (→).


b
Moving the cart on Track 2 one space to the left (←).


c
Moving the cart on Track 2 one space to the right (→).

d
All these movements will result in the same change in potential energy because they each move a cart the same distance.

Determine the mechanical energy of this object. A 2 kg pendelum has a speed of 1 m/s at a height of 1/2 meter
Readme [11.4K]

Mechanical Energy: 10.81 J given that g = 9.81 \; \text{m}\cdot\text{s}^{-2}.

<h3>Explanation</h3>

The mechanical energy of an object is the sum of its kinetic and potential energy.

Kinetic Energy of this object:

\text{KE} = \dfrac{1}{2} \; m \cdot v^{2} = \dfrac{1}{2} \times 2 \times 1 = 1 \; \text{J}

Gravitational Potential Energy of this object:

g = 9.81 \; \text{m}\cdot\text{s}^{-2}.

\text{PE} = m \cdot g \cdot h = 2 \times 9.81 \times \dfrac{1}{2} = 9.81 \; \text{J}.

Two friends leave a movie theater and take different busses to the same ice cream shop. one bus takes a longer route driving on
irinina [24]

The friend who has the greater displacement is the one who takes the longest path.

<h3>What is displacement?</h3>

The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.

Given, two friends leave a movie theater and take different buses to the same ice cream shop. One bus takes a longer route driving on a high-speed highway, while the other takes a shorter route on lower-speed local roads.

According to the definition. the displacement is neither larger not shorter but it is the shortest distance traveled by the person or particle.

Thus, friend who has longer path has larger displacement.

Learn more about displacement.
