ASAP PLEASE An object accelerates from a stop at 5m/s^2 to the east. After 10 seconds it reaches its maximum velocity. After another 75 seconds it turns back toward the starting point. It immediately slows down and moves at 15m/s until it reaches the start point where it stops.

A. What is the avg velocity of the object

B. How Far East does the object travel?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

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
