Physic its urgent1/ what is the total distance traveled by the object during the first 3 second2/what is the average speed of the object during the following interval in t=6 sec and t= 8 sec

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

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

The built in flash in a compact camera is usally capable of giving correct exsposure for distance up to how many meters?
