Question 1

1.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

What is the period of this wave?

T = 16 seconds

T = 8 seconds

ƒ = 16 seconds

ƒ = 8 seconds

Question 2

2.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

How many complete cycles are shown?

1 complete cycle

2 complete cycles

4 complete cycles

Question 3

3.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

What is the amplitude?

A = 1.0000 meters

A = 1.0000 seconds

A = 2.0000 meters

A = 2.0000 meters

Question 4

4.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

What is the displacement at 5 seconds and at 11 seconds?

when t=5 s, s = 0.7000; when t=11s, s=0.7000 m

when t=5 s, s = -0.7000; when t=11 s, s = -0.7000 m

when t=5 s, s = -0.7000; when t=11 s, s = 0.7000 m

when t=5 s, s = 0.7000; when t=11 s, s = -0.7000 m

Question 5

5.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

List all of the times in which the graph cuts through equilibrium.

When t=4 and 12 seconds

When t=4, 8 and 12 seconds.

When t=0, 4, and 12 seconds.

When t=0, 4, 8, 12, and 16 seconds.

Question 6

6.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

What is the frequency of the pendulum?

ƒ = (2 waves)/(8 secs) = 0.25

ƒ = (4 waves)/(8 secs) = 0.5

ƒ = (2 waves)/(16 secs) = 0.125

ƒ = (4 waves)/(16 secs) = 0.25

When t=4 and 12 seconds

When t=4, 8 and 12 seconds.

When t=0, 4, and 12 seconds.

When t=0, 4, 8,12, and 16 seconds.

Question 8

8.

This is a graphical representation of a pendulum that is hanging from the edge of a tall office building.

List the times that show maximum kinetic energy.

When t=4, 8 and 12 seconds.

When t=0, 4, 8,12, and 16 seconds.

When t=0, 4,12, and 16 seconds.

Question 9

9.

List the times that show maximum Potential energy.

When t=2 and t=10

When t=6 and t=14

When t=0, 4, 8, 12, 16 seconds

When t=2, 6, 10, 14 seconds
