WebA boy of mass 43.2 kg runs and jumps onto a stationary skateboard. The boy lands on the skateboard with a horizontal velocity of 4.10 m/s. 5 (a) (I) Add To Classified ... Using ideas about conservation of momentum, calculate the combined. velocity of the boy and skateboard just after the boy lands on it. WebAn impulse is responsible for the change in momentum. This comes from the gravitational force acting parallel to the inclined plane. The force of the inclined plane and the box exert equal and opposite forces at the same time, making the impulses equal and opposite. Because of this, the momenta are equal and opposite and the conservation of ...
