While riding his bike, Riley was able to travel 10 km from his house. He began his journey at the end of his
driveway and rode up a hill for 3 blocks before making
a right-hand turn. He continued for 4.8 km before
turning around and returning home. The entire trip
took Riley 25 minutes. Which of the following
correctly describes the average speed of his bike ride?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
