Solution Steps

Step 1: Understanding the Pendulum Motion

A pendulum swings back and forth, converting gravitational potential energy (GPE) to kinetic energy (KE) and vice versa. At the highest point of the swing, the pendulum has maximum GPE and zero KE. At the lowest point, it has maximum KE and zero GPE.

Step 2: Analyzing the Initial and Final Energy States
  • Initial State (Highest Point on the Left Side):
    • Maximum GPE
    • Zero KE
  • Final State (Lowest Point at the Center):
    • Zero GPE
    • Maximum KE
Step 3: Matching the Energy States with the Graphs
  • Graph A:
    • Initial: High GPE, Zero KE
    • Final: Zero GPE, High KE
  • Graph B:
    • Initial: High KE, Zero GPE
    • Final: Zero KE, High GPE

Final Answer

The correct graph that represents the energy flow from the highest point to the lowest point is Graph A.

Steve decided to invite friends over to watch the football game and ordered pizzas. The total bill was 50.81, and he gave the driver a 15% tip. Step 1 of 2: What amount did he give the driver as a tip? Follow the problem-solving process (The short method for calculating 15% tip should be used.) and round your answer to the nearest cent if necessary.

A block with mass m1 hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m2 that sits on a ledge slanted at an angle of 20° (see figure below). Suppose the system of blocks is initially held motionless and, when released, begins to accelerate. (a) If m1=7.25 kg, m2=3.00 kg, and the magnitude of the acceleration of the blocks is 0.170 m / s^2, find the magnitude of the kinetic frictional force between the second block and the ledge. (b) What is the value of the coefficient of kinetic friction between the block and the ledge?
