Two children stand on opposite sides of a merry-go-round of diameter 6.0 m which is rotating at an angular velocity 12 revolutions per minute. One child throws a ball of mass m=0.50 kg at a speed v=6.0m/s directly toward the other child.
a) Calculate the magnitude of the Coriolis force acting on the moving ball due to the rotation of the merry-go-round,
b) Determine the distance by which the ball misses the second child, i.e., the lateral deflection of the ball after it has traveled across the merry-go-round.
What is the necessary metabolic power? Hint: You can model her power needs as the sum of the power to walk on level ground plus the power needed to raise her body by the appropriate amount. Express your answer to two significant figures and include t..
