Question 1031288: The equation below expresses the approximate height,"h", in meters, of a coin "t" seconds after it is flipped vertically upward
from a height of 1.5 meters with an initial velocity of 1 meter per second. After how many seconds will the coin land on the ground ?
h=-4.9t^2+t+1.5 Answer by ikleyn(52778) (Show Source):

The equation below expresses the approximate height,"h", in meters, of a coin "t" seconds after it is flipped vertically upward
from a height of 1.5 meters with an initial velocity of 1 meter per second. After how many seconds will the coin land on the ground ?
h=-4.9t^2+t+1.5
~~~~~~~~~~~~~~~~~~~~~~~~~
Coin lands the ground <-----> h = 0.
So, solve the quadratic equation = for t, and you will get the answer.
Use the quadratic formula.
