Newton's third law states that when an object exerts force on another object, the second object exerts an equal but opposite force on the first object. which of the following shows an example of this
a. a girl hits a volleyball. her hand exerts a force on the ball, and the ball exerts a force on her hand.
b. a woman presses on both sides of a box with equal force.
c. a moving cart becomes more difficult to stop as more mass is added to it.

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = β16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
