  • Bounce Height Problem: When Will a Ball Fall Below 2 Meters?
    The ball bounces up to 7/10 of its previous height.

    So, after the first bounce, the ball reaches a height of 7 meters.

    After the second bounce, the ball reaches a height of 7 * 7/10 = 4.9 meters.

    After the third bounce, the ball reaches a height of 4.9 * 7/10 = 3.43 meters.

    After the fourth bounce, the ball reaches a height of 3.43 * 7/10 = 2.401 meters.

    After the fifth bounce, the ball reaches a height of 2.401 * 7/10 = 1.6807 meters.

    So, the ball will be below 2 meters after the fifth bounce.
