Question

a student is setting up an experiment with 10 different balls. the student wants to measure which ball hits the ground with the largest force when released from a box 5 feet above the ground. which quantity should be measured to correctly calculate the force with which each ball hits the ground? (1 point) the rate at which the velocity of each ball increases the mass of each ball the final velocity of each ball right before hitting the ground the initial velocity of each ball

Explanation:

Step1: Recall Newton's second - law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. In free - fall, the acceleration due to gravity $g$ is constant near the Earth's surface ($a = g$). To find the force with which the ball hits the ground, we need to know the mass of the ball as the acceleration is a known constant ($g\approx9.8\ m/s^{2}$ or $32.2\ ft/s^{2}$).

Answer:

the mass of each ball
