A box with a mass of 22.0 lg is placed on a ramp that is at 38.0 degrees above the horizaontal. Find the weight (Fg) of the box in N. Find the perpendicular force (Fgv) in N. Find the parallel force (Fgx) in N. Find the accreditation of the box in m/s^2. All answers should be in 3 SIG. FIG.

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
