PLEASE HELPPP Ball A of mass 5.0 kg moves at a speed of 4 m/s. It collides with a second stationary ball B, also
of mass 5.0 kg. After the collision, ball A moves off in the direction 45 degrees to the left of its
original direction. Ball B moves off in the direction 45 degrees to the right of ball A's original
direction.
a. Draw a vector diagram to determine the momentum of ball A and ball B after the collision.
b. What is the speed of each ball after the collision?

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) = −16t2 + 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
