A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where: s(t)=4.9t + 34.3t and t is in seconds
A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where:s(t)=4.9t + 34.3t and t is in seconds. If a stone is thrown downward at 34.3m/sec from a height of 294 m, how long will it take the stone to reach the ground?I am putting 294 in for t and trying to solve it that way. Is this correct? If not please let know where I am going wrong.
