Review A Bookmark Stewart, Justin Physics: Unit 3- Energy / 1 of 4/ Activity 1 Task: Potential & Kinetic Energy Activity 1 of 5 At what point in this roller coaster does the roller coaster have the most gravitational potential energy? A roller coaster starts from rest at point A. The mass of the cart with O A. Point A riders is 900 kg. The motor of the roller coaster does work to get the car up the hill to point B. From point B, the car relies on energy transformations to make it through the rest of the shown portions of the roller coaster. [g=9.8 m/s²] B. Point B C. Point C O D. Point D A

A small block of mass 200 g starts at rest at A and slides along a curved frictionless track surface to B, then slides along the horizontal surface a distance 10 m before coming to rest at C due to friction between B and C. Find its speed at B and the work done by friction along the horizontal surface from B to C. 4.0 m B -10 m-

A 1.85 kg book is sliding along a rough horizontal surface. At point A it is moving at 3.50 m/s, and at point B it has slowed to 1.45 m/s. 1. If -0.700 J of work is done on the book from B to C, how fast is it moving at point C? 2. How fast would it be moving at C if 0.700 J of work were done on it from B to C?
