Question
A child is swinging back and forth on a swing. Her maximum height in this motion is
1.60 m above her lowest height. After she has reached her maximum height, she
begins to travel a direction 32.0 degrees below the horizontal. What is the speed of
her centre of mass at the lowest point in her motion where she is travelling
horizontally? Consider the swing to be frictionless and massless.
