1)with the idea of conservation of momentum explain why a golf ball leaves the surface of a golf club at a much greater velocity that the club was moving before it hit the ball?
2)Single charged sodium ions are accelerated through a potential difference of 398 V. (a) What is the momentum acquired by such an ion? kg*m/s (b)What is the de Broglie wavelength? Fm
3)A body of mass 5.0kg is pulled on a smooth plane inclined at 30° to the horizontal by a force of 40N acting parallel to the plane .calculate the acceleration of the body and the force exerted on it by the plane
