Marla rolled a basketball into a soccer ball the blue arrow represents the speed of the basketball as it rolled toward the soccer ball after the collision how did the speed of the two balls change note that the size of the arrow indicates the speed of the ball
Without more specific information or measurements, it is not possible to determine how the speed of the basketball changed after the collision with the soccer ball.
Based on the given information, we can assume that Marla rolled a basketball towards a stationary soccer ball, and the blue arrow represents the speed of the basketball. After the collision, we need to determine how the speed of the two balls changed.
There are different scenarios that can occur depending on the conditions of the collision. We can think of three possible scenarios:
1. Elastic Collision: In an elastic collision, both the momentum and energy are conserved. As a result, the soccer ball may acquire some velocity (represented by an arrow) in the direction of the basketball's initial velocity, while the basketball may lose some velocity after the collision. The size of the arrows would depend on the masses of the two balls.
2. Inelastic Collision: In an inelastic collision, the two objects stick together after the collision. In this case, the basketball and the soccer ball would move together with a common velocity. The size of the resulting arrow would be a combination of the initial velocities of the two balls.
3. Perfectly Inelastic Collision: In a perfectly inelastic collision, the two objects stick together and move as one mass after the collision. The resulting velocity would be determined by the masses of the two balls.
Without more specific information about the masses of the basketball and the soccer ball, it is not possible to determine exactly how the speed of the two balls changed after the collision.
To determine how the speed of the two balls changed after the collision, you need to understand the concept of conservation of momentum. The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces act on it.
In this scenario, Marla rolled a basketball into a soccer ball, which means the system includes both balls. Initially, only the basketball was moving, so its momentum was non-zero, while the soccer ball was at rest.
When the basketball collides with the soccer ball, they exert forces on each other. According to Newton's third law, the forces are equal in magnitude and opposite in direction. These forces cause an exchange of momentum between the balls, and their total momentum remains constant.
Since the basketball is rolling into the soccer ball, it exerts a force on it, causing the soccer ball to move and gain momentum. Thus, the soccer ball's speed increases after the collision.
On the other hand, the basketball transfers some of its momentum to the soccer ball, causing its speed to decrease. However, it is important to note that the total momentum of the system remains the same.
The change in speed of the two balls can be observed through the sizes of the arrows. As the basketball's speed decreases, its arrow size would become smaller. Conversely, the soccer ball's speed increases, resulting in a larger arrow size.
In summary, after the collision between the basketball and soccer ball, the basketball's speed decreases while the soccer ball's speed increases.
