With your group: 1. Decide on the key events for the problem. 2. Label the events on the picture above. 3. Explain to each other the physics during each interval within the problem. You may write on this page. This group work will not be marked. A detailed question with numbers will follow in 10 minutes. ࠵?⃑!= ࠵?⃑"+ ࠵?⃑∆࠵?∆࠵?⃑= ࠵?⃑"∆࠵? +࠵?⃑∆࠵?!2∆࠵?⃑= ࠵?⃑!∆࠵? −࠵?⃑∆࠵?!2∆࠵?⃑=(࠵?⃑"+ ࠵?⃑!)∆࠵?2࠵?⃑!!= ࠵?⃑"!+ 2࠵?⃑∆࠵?⃑Kinematics Formative CGPS Name: Curling is a sport where players send a rock down a sheet of ice towards the scoring area at the other end. The Castlebrooke Ice Curling team wants to stay ahead of the rest of Peel Region and maintain ROPSSAA dominance in the sport. To do so, they hire you, a physicist, to help improve their strategy. The curler starts at the hack. They push the stone to accelerate it from rest to its maximum speed. The curler then releases the stone at or before the hogline so it can travel down the ice to the scoring area. The team would like you to help them predict the motion of the stone under certain conditions. hack hogline The house

Kinematics Formative CGPS Name: The curler stands in the hack at one end of the ice. After pushing the stone a distance of 10.1 m, the curler releases the stone at the hogline, and it travels towards the button. The stone takes 11.2 s to reach the button, 28.3 m away from the hogline. The stone is moving at 1.07 m/s when it reaches the button. i)What was the acceleration of the stone while being pushed? ii)How much time is the stone pushed for? A: Pictorial Representation [LM3] Sketch showing events, describe events, coordinate system, label givens & unknowns with symbols, conversions B & C: Physics & Word Representation Fully explain answers. Focus on physics vocabulary, symbols and relevant clarifications. Evidence of high-quality thinking. All written work is: °correct °clear °concise °complete 1.Use a position-time graph and velocity vectors to describe the curling stone’s state of motion in both intervals. Be sure to refer to bothrepresentations with your words. [LM2]2.Are unit conversions needed to solve this problem? Explain. [LM1] 3.A student describes event 1 as “curling stone is speeding up”. What advice would you give them? [LM3]
4.A friend produces the motion diagram and acceleration-time graph shown below. What advice would you give them? Include corrected representations. [LM2]Advice: 5.If the stone was released sooner, how would this affect its speed at the button? A velocity-time graph for the stone’s original motion is shown. Use this grid to draw the graph and refer to the graphs in your explain. [LM3]E: Evaluation [LM1] Answer has reasonable size, direction and units? Explain why for firstcompleted calculation.
