Written Challenge Problem, 2D Kinematics: Snowballs are thrown with a speed of 19 m/s from a roof 7.0 m above the ground. Snowball A is thrown horizontally; snowball B is thrown in a direction 35° above the horizontal. Find the direction of motion (that is, the angle of the velocity vector) of each of the two snowballs just before they land. 1) Draw a pictorial representation of the problem. 2) Choose a coordinate system. Remember to identify where the origin is. 3) Sketch out qualitative graphs of the trajectory for both snowballs. 4) List the variables given, variables needed, and any simplifying assumptions being made. Translate information you've been given on vectors in polar form, into cartesian form. 5) Write out the general kinematic equations you will use to solve the problem. 6) Solve algebraically for the variables you need. 7) Comment briefly on whether your result is reasonably believable. If it is- what sort of result could be easily identified as not believable for this problem?
