toes. A Ballet dancer puts all her weight on the toes of one foot. If her mass is 60 kg, what is the force that has to be exerted by her leg muscle to hold that pose? Assume the pivot is at the toes.

The force is  

Explanation:

The diagram for this question is shown on the first uploaded image

 From the question we are told that

   The mass of the dancer is  

From the diagram the

      The first distance is

      The second distance is  

At equilibrium the moment about the center of the dancers  feet  is mathematically represented as

   Where

substituting values

=>    

=>      

volts times amps 6 x 0.5 3w

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
