Help please
I don't know how to start this problem
If a rock is thrown upward on the planet Mars with a velocity of 10 m/s, its height (in meters) after t seconds is given by H = 10t - l.86t2. Find the velocity of the rock after one second. Find the velocity of the rock when t = a. When will the rock hit the surface? With what velocity will the rock hit the surface? Show transcribed image text
