An automobile with a mass of 1450 kg is parked on a moving flatbed railcar; the flatbed is 1.50 m above the ground. the railcar has a mass of 38500 kg and is moving to the right at a constant speed of 8.70 m/s on a frictionless rail. the automobile them accelerates to the left, leaving the railcar at a speed of 22.0 m/s with respect to the ground. when the automobile lands, what is the distance d between it and the left end of the railcar?

The energy produced as a result of this flow of electrons from atom to atom is called

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
