How much force does it take to make a tennis ball travel 10 meters?
I have to build a catapult for my physics class and we must launch our tennis ball 10 meters. I have constructed my catapult, however the tennis ball only goes maybe 5-10 feet. so how could i make it stronger?
Depends on how you've constructed it to begin with.
One possibility is to increase the length of the launching arm. This will increase the velocity of the end of the arm, increasing the ball's velocity.
If you're using some sort of spring (e.g., rubber band), perhaps you can find stiffer springs.
Perhaps you can elongate your existing springs more (Hooke's law: F = kx).
If your catapult slides back at launch, perhaps you can prevent it from doing so.
Perhaps you can adjust the launch angle -- maximum distance is achieved when the angle is 45º.
Hope that helps.
