± Gravity on Another Planet
After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 53.0 cm. The explorer finds that the pendulum completes 90.0 full swing cycles in a time of 142 s.
Part A
What is the magnitude of the gravitational acceleration on this planet?
g planet =
Properties of Ocean Waves
A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.10 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m. The fisherman sees that the wave crests are spaced a horizontal distance of 5.90 m apart.
Part A
How fast are the waves traveling?
v=
Part B
What is the amplitude A of each wave?
A=
