Question
A stone is thrown upward from the edge of a cliff, reaches its maximum height, and then falls down into the valley below. A motion diagram for this situation is given , beginning the instant the stone leaves the thrower’s hand. Construct the corresponding motion graphs taking the acceleration due to gravity as 10 . Ignore air resistance. In all three motion graphs, the unit of time is in seconds and the unit of displacement is in meters. In plotting the points, round-off the coordinate values to the nearest integer.
I already have part A. I really need help in how to find the points I need to graph in part B and C. Please help me!!!
Explanation / Answer
a = -10 v = -10t + C at t=2, v=0 0 = -10(2) + C C = 20 v = -10t + 20 y = -5t^2 + 20t motion graphs come from those 3 equations. :)
