Chuck drops a rock from a height of 70 m. How long will it take the rock to hit the ground?

Use the formula h(t)=−4.9t^2+v0t+h0
, where v0 is the initial velocity and h0 where v0 is the initial velocity and h0 is the initial height.

We just started the introduction into circles and i have no idea how to do this.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
