Question 1166363: An object tossed downward with an initial speed (Velocity) of V. will travel a distance of s meters, where =4.9t^2+V.t, anf t is measured in seconds. A coi is dropped from a helicopter at an altitude of 75 m. Approximately how long does it take the coin to reach the ground?

The term  "dropped"  means that the initial velocity was zero : V = 0.


Therefore, to solve the problem, you need to solve this equation


    4.9t^2 = 75.


The solution is  t =  seconds.

Use your calculator.
