如右图所示装置可用来验证机械能守恒定律。摆锤A拴在长L的轻绳一端，另一端固定在O点，在A上放—个小铁片，现将摆锤拉起，使绳偏离竖直方向成θ角时由静止开始释放摆锤，当其到达最低位置时，受到竖直挡板P阻挡而停止运动，之后铁片将飞离摆锤而做平抛运动。

小题1:为了验证摆锤在运动中机械能守恒，必须求出摆锤在最低点的速度。为了求出这一速度，实验中还测量了遇到挡板之后铁片的水平位移S和竖直下落高度h。根据测得的物理量表示摆锤在最低点的速度v=                                  

小题2:根据巳知的和测得的物理量，写出摆锤在运动中机械能守恒的关系式为         。

     Having returned from her round trip, the angry woman stood outside the ticket office of the station. "The

railway owes me￡12," she said to Harry Jenks, the young man working at the office. "You sold me a ticket

for May 22nd, but there was no ship from Jersey that night. So my daughter and I had to stay in a hotel. It

cost me 12."

     Harry was worried. He remembered selling the woman a return ticket. "Come into the office, Madam," he

said politely. "I'll just check the Jersey timetable for May 22nd."

     The woman and her little girl followed him inside. She was quite right, as Harry soon discovered. There

was no sailing on May 22nd. How could he have made such a careless mistake? He couldn't have sold her a

ticket for that day. Wondering what to do, he smiled at the child. "You look sunburnt," he said to her. "Did

you have a nice holiday in Jersey?"

     "Yes," she answered, shyly. "The beach was lovely. And I can swim too."

     "That's fine," said Harry. "My little girl can't swim a bit yet. Of course, she's only three..."

     "I'm four," the child said proudly. "I'll be four and a half."

     Harry turned to the mother. "I remember your ticket, Madam," he said. "But you didn't get one for your

daughter, did you?"

     "Er, well..." the woman looked at the child. "I mean...she hasn't started school yet. She's only four."

     "A four-year-old child must have a ticket, Madam. A child's return ticket to Jersey costs...let me see...

￡13. 50. So if the railway pays your hotel, you will owe the railway 1.50. The law is the law, but since the

fault was mine..."

     The woman stood up, took the child's hand and left the office.
