If a rock is thrown upward on the planet mars with the velocity of 10 m/s its height in meters t seconds later is given by y = 10t - 1.86t^2. Find the average velocity over the given time intervals.
If you could explain the answer and how you went about getting it that would be really helpful
Plug '1' into the equation to get the height at t = 1
Plug '3' into the equation to get the height at t = 3
this is an interval of two seconds
then (height3 - height1 ) / 2 = average velocity over the interval from 1 to 3 sec
the others are similar ....
