The figure below shows a titanium ball with a mass of 3.30 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v = 10.0 m/s), and the angle its path makes with the wall is ? = 60.0°as shown. (Because we are analyzing the motion of the ball over a very short time just before and after impact, you may safely ignore the effect of gravity on the ball.) The ball is in contact with the wall for 0.206 s. What is the average force (in N) exerted by the wall on the ball during the impact

Question

The figure below shows a titanium ball with a mass of 3.30 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v = 10.0 m/s), and the angle its path makes with the wall is ? = 60.0°as shown. (Because we are analyzing the motion of the ball over a very short time just before and after impact, you may safely ignore the effect of gravity on the ball.) The ball is in contact with the wall for 0.206 s. What is the average force (in N) exerted by the wall on the ball during the impact

 

The image depicts a basic physics concept related to reflection. It shows a vertical boundary, such as a mirror, aligned along the y-axis with an incoming object approaching at an angle, denoted as \(\theta\), to the surface. 

Key elements of the diagram include:

- **Object Representation**: Two identical spheres represent the object before and after reflection.
- **Incident and Reflected Paths**: Dashed lines indicate the paths of the incident and reflected rays. The incoming and outgoing paths are symmetrical with respect to the normal line, which is perpendicular to the boundary.
- **Angle of Incidence and Reflection**: Both angles are marked as \(\theta\), illustrating that the angle of incidence is equal to the angle of reflection, a fundamental principle of reflection.
- **Arrows**: The red arrows demonstrate the direction of movement for both the incoming and reflected rays.

This diagram helps in understanding the law of reflection, which states that the angle of incidence is equal to the angle of reflection when a wavefront, like light or sound, bounces off a reflective surface.
