उत्तर

  1. When the fielder lowers his hands backward, he increases the value of time of the collision and so retardation is decreased.
  2. Hence retarding force becomes lesser than before and the palm of the fielder is not hurt very much.

According to the third law of motion, when we push on an object, the object pushes back on us with an equal and opposite force. If the object is a massive truck parked along the roadside, it will probably not move. A student justifies this by answering that the two opposite and equal forces cancel each other. Comment on this logic and explain why the truck does not move.
