# Exciting Soccer Ball Physics Challenge!

**Challenge:**A soccer ball is kicked flat on the ground by a UNO player. She kicks the ball with an initial velocity of 6m/s. The ball then travels untouched until it stops 48ft away. Can you calculate the following: a. How much acceleration does the grass impart as it slows the ball? b. How long does it take the ball to come to rest? c. How far will the ball have traveled when it has a velocity 28% of its initial velocity?

**Answer:**a. The grass imparts an acceleration of 0.36 m/s² to the ball as it slows down. b. The ball takes 2.5 seconds to come to rest. c. When the ball has a velocity 28% of its initial velocity, it will have traveled 16.8 feet.

Let's dive into the exciting world of soccer ball physics! When the UNO player kicks the ball with an initial velocity of 6m/s, the ball starts its journey across the ground. As the ball moves, the grass imparts an acceleration to slow it down.

The grass imparts an acceleration of 0.36 m/s² to the ball, gradually bringing it to a stop. This deceleration causes the ball to eventually come to rest after 2.5 seconds of travel.

Now, let's calculate how far the ball will have traveled when it reaches a velocity of 28% of its initial velocity. At that point, the ball would have covered a distance of 16.8 feet.

So, in this thrilling soccer ball physics challenge, we've unraveled the secrets behind the acceleration, time taken to stop, and distance traveled by the ball. Soccer physics is truly a fascinating field to explore!
