Write a free-response answer, and Mia marks it
Type your answer to a question in one of the exam's four types, describing any diagram or graph in words. Mia marks every point, quotes the words that earned it and shows a full-credit answer.
Plan 2027 by unit weight
Units are not worth the same: forces and energy are 18–23% of Section I each, oscillations and rotating systems 5–8%. Set your hours and how sure you are of each unit, and get a week-by-week plan to May 5.

Question 2
A block is pushed against a spring on a frictionless level track and released. It leaves the spring and slides up a frictionless ramp. The energy bar chart shows the block-spring-Earth system while the spring is compressed, with Ug = 0 on the level track. At a point on the ramp, the block's speed is half its speed on the level track. Which describes the system's energy at that point?
Question 3
A 0.15 kg ball at rest is struck by a club. The graph shows the force of the club on the ball as a function of time. Ignoring other forces during the brief contact, what is the ball's speed when it leaves the club?
Question 4
Water flows at 1.5 m/s through a horizontal pipe of radius 2.0 cm that narrows to a radius of 1.0 cm, as shown. What is the speed of the water in the narrow section?
