medium vibrates at right angles to the direction the energy moves
medium vibrates in the same direction as the direction the energy moves
R = 200 Ω
V = I R
P = I V
V = 100 V
V = I R
R1 = 2 Ω
V = 10 V
Voltage is equal at both resistors

(direction is important)
kgm / s
which would you stand in front of?
Broken bones, pain…
How you change the momentum
(piggy back ride)
Go to pg. 506
A 65 kg swimmer runs with a horizontal velocity of 5.6 m/s off a dock
He jumps into a 15 kg rubber raft that is drifting towards him with a velocity of 1.0 m/s
What is the velocity of the swimmer and raft after the impact? (assume no friction or resistance due to air or water)
notice the subscripts
How will v1f compare to v2f?
only one vf
which direction is vf?
