Physics 125 Discussion #4 1 Problem 1: A body projected horizontally A motorcycle stunt rider rides off the edge of a cliff. Just at the edge his velocity is horizontal, with magnitude 9.0 m/s. x direction y direction initial position x 0 = y 0 = initial velocity v 0x = v 0y = acceleration a x = a y = (3) What is the motorcycle’s position ( x , y ) at t = 0.50 s? (1) First, let’s define our coordinate system. The coordinate system is shown in the figure. We choose the origin at the edge of the cliff, where the motorcycle first becomes a projectile. (2) List all the known factors (in both x- and y- directions). 0 v h x y O
