If an object is given an initial velocity straight upward of v0 feet per second from a height of s0 feet , then its altitude's after 1 second is given by the formula:
S= -16t2+ v0t + s0.
An arrow is shot straight upward with a velocity of 96 feet per second (ft/sec) from an altitude of 6 feet. For how many seconds is this arrow more than 86 feet high.© BrainMass Inc. brainmass.com October 9, 2019, 8:11 pm ad1c9bdddf
Studying the given formula and the data carefully, we can observe that we are given the initial velocity v0=96, height s0=6. The altitude after 't' ...
