MomentumName: __Isaiah Robinson____________________________________Date: ________________________Student Exploration2D CollisionsGo to CLEVER, 2-D Collisions, LAUNCH:Highlight your answersGizmo Warm-upObjects collide all the time, but often with very different results. Sometimes colliding objects will stick together. Other times, they will bounce off each other at an angle. What determines how objects will behave in a collision? You can use the 2D CollisionsGizmo to find out.Note the arrows, or vectors, on each puck. Click Play(1.How does the direction and length of its vector relate to the motion of a puck? ___________).
2.The velocity(speed and direction) of each puck is described by components in the i and directions. The symbol for velocity is v. (Vector quantities are shown in bold.)A.Which component represents movement in the east-west direction? jMB.Which component represents movement in the north-south direction? J3.The speed(v) of a puck is equal to the length of its velocity vector. To calculate the speed ofa puck with a velocity of ai + bj, use the Pythagorean theorem: v=a2Set the velocity of the blue puck to 12.00i+ 5.00jm/s. What is its speed? +b2
