A 500
Identify the frame of reference:
A football player crosses the goal line and scores a touchdown.
David grandmother’s house is 4 kilometers away. It took
him 30 minutes to bicycle to his grandmother’s house.
What was his speed in km/hr?
B 500
You are paddling a canoe at a speed of 10 m/s downstream.
If the water’s current has a velocity of 20 m/s
downstream, how fast are you traveling?
C 300
C 400
You are on an airplane traveling 300 miles/hour
west. The wind that you are flying through has a velocity of 100 miles/hour east. What
is your velocity?
You are paddling 15 m/s upstream of a river. The
current of the river is moving at 20 m/s downstream. What
is your overall velocity?
C 500
A merry-go-round is traveling at a constant speed of 2 m/s. Is the
merry-go-round accelerating?
D 200
YES. Even though it is moving at a constant speed, it is moving in a circular path so it is always
changing direction.
D 400
Assuming that each cyclist did not change direction during the race, which
cyclist had no acceleration?
