... Both objects reach the same speed at the floor. However, while the beanbag comes to rest on the floor, the ball bounces back up with nearly the same speed as it hit. Thus, the change in momentum for the ball is greater, because of the rebound. The impulse delivered by the ball is twice that of the b ...

... “As you approach the 30th floor, the elevator will start to slow down. As the elevator slows down it means that the acceleration is downwards, therefore you press less hard on the elevator floor then before. That’s why in really fast elevators sometimes you feel a little weightless or a funny feelin ...
