The velocity of a particle traveling along a straight line is v = vo − ks where k is constant. if s=0 when t=0, determine the position and acceleration of the particle as a function of time.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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
