一道物理判断题 学渣求大神帮帮看This problem has analogies in the game of pool.Puck 1 slides on a horizontal,frictionless surface with velocity&v&and collides elastically with stationary puck 2; each puck has the same mass,&m.The pucks move off with velocities&v1&and&v2,as shown.The angles θ1&and θ2&are measured relative to the initial direction of puck 1.Answer true or false to
e.g.,if the first one is true and the rest are false,enter TFFFF.&v2& = &v1cos2θ1+v2cos2θ2This problem has analogies to pool because pool balls have equal mass and roll without friction.[As long as rotational KE of pool balls is neglected,the analogy is perfect.]In this problem,kinetic energy is conserved but linear momentum is not conserved.If&a+b& = &c&for three non-zero vectors,and&a2+b2& = &c2,then the angle between&a&and&b&is 90°.v& = &v1cos2θ1+v2cos2θ2
FTFT这是非对心碰撞需要把v1正交分解到沿圆心连线方向
v1cosθ2和垂直于圆心连线方向
v1cosθ1其中沿连线方向交换动量,由于质量相等,就是交换速度,所以v2= v1cosθ2最后一个等式v表示什么,没看到,所以无法判断像这种题有没有更好更快的解题方法。求大神解答，本人学渣一个。 _百度作业帮
