In a circus stunt that went horribly wrong the “splat brothers” below inadvertently fired their cannons simultaneously but at different angles (30\u00b0 and 60\u00b0). 146 Fortunately there were no drag forces acting on the day and both cannons fired the performers at the same speed. Unfortunately the brother fired at 60\u00b0 is twice as heavy as the brother fired at 30\u00b0. Who lands first? The heavy brother The lighter brother They both land at the same time<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is: The lighter brother lands first<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

In projectile motion, the time of flight of an object is determined by the vertical<\/strong> component of its velocity and the acceleration due to gravity. Since air resistance is ignored, the only force acting on the performers after they are launched is gravity.<\/p>\n\n\n\n

Let\u2019s define the parameters:<\/p>\n\n\n\n

    \n
  • Both brothers are launched at the same speed<\/strong> ( v_0 ).<\/li>\n\n\n\n
  • The launch angles are 30\u00b0<\/strong> and 60\u00b0<\/strong>.<\/li>\n\n\n\n
  • The heavier brother has twice the mass<\/strong> of the lighter brother.<\/li>\n\n\n\n
  • Gravity acts downward with an acceleration of ( g )<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    The time of flight<\/strong> of a projectile is given by:<\/p>\n\n\n\n

    [
    T = \\frac{2 v_0 \\sin \\theta}{g}
    ]<\/p>\n\n\n\n

    where:<\/p>\n\n\n\n

      \n
    • ( v_0 ) is the launch speed,<\/li>\n\n\n\n
    • ( \\theta ) is the launch angle,<\/li>\n\n\n\n
    • ( g ) is acceleration due to gravity.<\/li>\n<\/ul>\n\n\n\n

      Step 1: Calculate Time of Flight for Each Brother<\/h4>\n\n\n\n

      For the lighter brother<\/strong> (30\u00b0 launch angle):<\/p>\n\n\n\n

      [
      T_{30} = \\frac{2 v_0 \\sin 30^\\circ}{g}
      ]<\/p>\n\n\n\n

      Since ( \\sin 30^\\circ = 0.5 ):<\/p>\n\n\n\n

      [
      T_{30} = \\frac{2 v_0 (0.5)}{g} = \\frac{v_0}{g}
      ]<\/p>\n\n\n\n

      For the heavier brother<\/strong> (60\u00b0 launch angle):<\/p>\n\n\n\n

      [
      T_{60} = \\frac{2 v_0 \\sin 60^\\circ}{g}
      ]<\/p>\n\n\n\n

      Since ( \\sin 60^\\circ = 0.866 ):<\/p>\n\n\n\n

      [
      T_{60} = \\frac{2 v_0 (0.866)}{g} = \\frac{1.732 v_0}{g}
      ]<\/p>\n\n\n\n

      Step 2: Compare the Times<\/h4>\n\n\n\n

      Clearly,<\/p>\n\n\n\n

      [
      T_{60} > T_{30}
      ]<\/p>\n\n\n\n

      which means the heavier brother stays in the air longer<\/strong>.<\/p>\n\n\n\n

      Step 3: Mass Dependency<\/h4>\n\n\n\n

      Mass does not<\/strong> affect the time of flight in projectile motion (as long as there\u2019s no air resistance). Gravity acts equally on all objects regardless of mass.<\/p>\n\n\n\n

      Thus, since the brother launched at 60\u00b0 stays in the air longer<\/strong>, the lighter brother (30\u00b0) lands first<\/strong>.<\/p>\n\n\n\n
