The basketball is gaining kinetic and losing potential energy is the answer


Radda [10]3 years ago
4 0

Answer: Option (A) is the correct answer.

Explanation:

Kinetic energy is the energy obtained by an object due to the motion of its particles. Whereas potential energy is the energy obtained by an object due to its position.

At point A basket ball is at rest so, it will have maximum kinetic energy.

When the basket ball bounces from position A to position B then potential energy will convert into kinetic energy.

Thus, we can conclude that as the basketball bounces up from A to B it is gaining kinetic energy and loosing potential energy as it bounces up.

reviews the approach taken in problems such as this one. A bird watcher meanders through the woods, walking 0.916 km due east, 0
Verizon [17]

Answer:

Displacement: 2.230 km    Average velocity: 1.274\frac{km}{h}

Explanation:

Let's represent displacement by the letter S and the displacement in direction 49.7° as A. Displaement is a vector, so we need to decompose all the bird's displacement into their X-Y compoments. Let's go one by one:

  • 0.916 km due east is an horizontal direction and cane be seen as  direction towards the negative side of X-axis.
  • 0.928 km due south is a vertical direction and can be seen as a direction towards the negative side of Y-axis.
  • 3.52 km in a direction of 49.7° has components on X and Y  axes. It is necessary to break it down using trigonometry,

First of all. We need to sum all the X components and all the Y componets.

∑Sx = Ax -0.916 ⇒  ∑Sx = [tex]3.52cos(49.7) - 0.916

∑Sx = 1.361 km

∑Sy = Ay - 0.918 ⇒ ∑Sy = 3.52sin(49.7) - 0.918

∑Sy = 1.767

The total displacement is calculated using Pythagoeran therorem:

S_{total} =\sqrt{Sx^{2}+ Sy^{2} } ⇒

S_{total} = 2.230 km

With displacement calculated, we can find the average speed as follows:

V = S/t  ⇒  V = \frac{2.230}{1.750}

V = 1.274\frac{km}{h}

Based on the graph, describe how momentum changes with time for an object in free fall. If you can help, I would be so grateful.
pochemuha
With time, momentum increases as it builds speed assuming their is nothing in the way to stop it. Based on the graph, you can see that example being displayed as the line on the graph gets higher
