9. ### 物理動量速速一問,,

物理學上必須在比較理想的狀態，故在兩物體相撞的情況下，必將一些如空氣阻力(以免速度減慢)、兩物體的表面平滑(以免摩擦力減慢速度)而堅硬(以免吸收其能量)等條件假設不考慮，則單單只計算 momentum比較簡單。

10. ### Physic motion Question (urgent) !!! ----20 pts

1) Consider: v = u + at u = v - at --- ( 1 ) s = ut + 0.5at^2 --- ( 2 ) Put ( 1 ) into ( 2 ), s = ( v - at )( t ) + 0.5 at^2 s = vt - at^2 + 0.5at^2 s = vt - 0.5at^2 ( 2 ) From the above, 58 = ( 12 )( 3 ) - ( 0. 5 )( a )( 3^2 ) 4.5a = -22 a = -4.89 m / s^2 ( cor. to 3 s.f. ) By v = u + at...
