5. You are surfing, but the waves are lame so you paddle back to shore. The waves are pushing you directly to the shore, but you are paddling at an angle, so that you get closer to where you parked your car. The waves are pushing you 10 ft/sec, and you are paddling 45° to the right at a speed of 5 ft/sec. (a) Draw a to scale vector diagram of this situation. Your diagram should include the vector describing the velocity from the waves, and the vector describing the velocity from your paddling. Label the scale of your drawing.

5.
You are surfing, but the waves are lame so you paddle back to shore. The
waves are pushing you directly to the shore, but you are paddling at an angle, so that
you get closer to where you parked your car. The waves are pushing you 10 ft/sec, and
you are paddling 45° to the right at a speed of 5 ft/sec.
(a)
Draw a to scale vector diagram of this situation. Your diagram should
include the vector describing the velocity from the waves, and the vector describing
the velocity from your paddling. Label the scale of your drawing.
(b),
On your drawing above, use the two given vectors to make a scale draw-
ing of their resultant vector. Then use the scale of your drawing to estimate the
magnitude of the resultant. Show the calculation of using the scale.
