9. Three friends were kicking soccer balls at a neighborhood field. Three soccer balls were rolling across the field. The black soccer ball has less mass than the blue and orange balls, which have equal mass. All three soccer balls were kicked by one of the friends, but not all from the same direction. Use the information in the diagram to answer.

Which soccer balls experienced the strongest force? How do you know?

Answers

Answer:

The Black soccer ball

Explanation:

The less mass is easier and have less density of air in it so the stronger it get kicked and reached.

Black ball, this is because the less mass an object has, the greater it is to move.

HELP ASAP!!! ( it’s science not physics) Allen, Chloe, Jaycee, and Kim are all biking at the same speed. At one point, Chloe speeds up and pedals at a new speed for several minutes. She slows down slightly as she rides up a hill. Finally, she slows way down to allow her friends to catch up with her.
The tables show the mass of each bicyclist, the kinetic energy (KE) of each bicyclist at the original speed, and the kinetic energy of Chloe at four different speeds.

Answers

Answer:

Answer: The chart for the bikers would start at (925,37) and end at (1250,50). The chart for Chloe would start at (200,2) and end at (4050,9). To also summarize the relationship shown in each graph you would want to put something like,  

1. The graph that shows the bikers mass and kinetic energy is linear. As the mass increases the kinetic energy also increases. The line on the graph is straight going up towards the right corner. The graph has about 64 squares making the line look smaller.

2. The graph shown shows Chloe’s speed and kinetic energy. The line on the graph is line. As the mass increases the kinetic energy also increases. The line on the graph is straight going up towards the right corner. The graph has about 25 squares making the line look bigger than the line shown on the first graph.
