Boxers attempt to move with an opponent's punch when it is thrown. In other words, a boxer moves in the same direction as their

opponent's punch. This movement may prevent a knockout blow being delivered by their opponent. Explain how.

Answer: h

Explanation:

Impulse is defined as the change of momentum of an object if the object is acted by a force for an interval of time. By delaying the time, the impact of the force can be reduced.

Boxers attempt to move with an opponent's punch when it is thrown. The force applied by the opponent's punch is extended over a longer time. Then the effect of the force of the blow can be reduced. In this case, the chances of a knockout blow being delivered by their opponent can be minimized.

When the force of the opponent's punch is extended, with time, the effect of the blow or the force of the blow is reduced thereby reducing chances for a knockout punch from the opponent to the boxer.

Answer:

    vₐ = v_c  ( \ 1 + \frac{1}{2} ( \frac{\Delta M}{M} - \frac{\Delta R}{R}) \ )

Explanation:

To calculate the escape velocity let's use the conservation of energy

starting point. On the surface of the planet

          Em₀ = K + U = ½ m v_c² - G Mm / R

final point. At a very distant point

         Em_f = U = - G Mm / R₂

energy is conserved

           Em₀ = Em_f

           ½ m v_c² - G Mm / R = - G Mm / R₂

           v_c² = 2 G M (1 /R -  1 /R₂)

if we consider the speed so that it reaches an infinite position R₂ = ∞

           v_c = \sqrt{\frac{2GM}{R} }

now indicates that the mass and radius of the planet changes slightly

            M ’= M + ΔM = M ( 1+ \frac{\Delta M}{M} )

            R ’= R + ΔR = R ( 1 + \frac{\Delta R}{R} )

we substitute

           vₐ = \sqrt{\frac{2GM}{R} } \  \frac{\sqrt{1+ \frac{\Delta M}{M} } }{ \sqrt{1+ \frac{ \Delta R}{R} } }

         

let's use a serial expansion

           √(1 ±x) = 1 ± ½ x +…

we substitute

         vₐ = v_ c ( (1 + \frac{1}{2}  \frac{\Delta M}{M} )  \ ( 1 - \frac{1}{2}  \frac{\Delta R}{R} ))

we make the product and keep the terms linear

        vₐ = v_c  ( \ 1 + \frac{1}{2} ( \frac{\Delta M}{M} - \frac{\Delta R}{R}) \ )
