1.) assuming the clay blob and the superball have the same mass, and that you throw them with the same velocity, which would you throw to close the door? the clay blob will stick to the door and the superball will bounce back with almost the same speed as it had before it collided with the door. which would be more effective at closing the door - the superball or the clay of the same mass?
2.) what is the final momentum of the clay ball?
3.) how do you find the impulse of a force from the force vs. time graph?
4.) in a perfectly elastic collision between a cart and a wall, the cart would recoil with exaclty the same magnitude of momentum that it had the before the collision. because your cart's spring bumper is not perfect, you can only produce a nearly elastic collision. why is the collision made with a "springy" wall?
5.) from the above question ( question 4) how will you measure the impulse?
