You toss a (wrapped) sandwich to a friend leaning out of a window 10 m above you, throwing just hard enough for it to reach her. at the same instant, she drops a silver dollar to you. at what position do the dollar and the sandwich pass each other?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

What is friction? how does it affect the motion of an object?

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
