After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 51.0cm . The explorer finds that the pendulum completes 109 full swing cycles in a time of 126s .
Part A Find the period of the pendulum
Part B What is the magnitude of the gravitational acceleration on this planet?
How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
