Achild blows a leaf straight up in the air from rest. the leaf accelerates at 1.0\,\dfrac{\text m}{\text s^2}1.0 s 2 m1, point, 0, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction upward. how much time does it take the leaf to displace 1.0\,\text m1.0m1, point, 0, space, m upwards?

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

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
